Extract reusable <DataInspector> component and fix class instance rendering

[TooTallNate]

Consolidate all ObjectInspector usage into a single DataInspector component
with shared theming, custom nodeRenderer for StreamRef/ClassInstanceRef, and
stream click context. Update all consumers (attribute-panel, events-list,
event-list-view, stream-viewer, conversation-view) to use DataInspector
instead of direct ObjectInspector or JSON.stringify. Fix class instance
hydration to create objects with dynamically-named constructors so
react-inspector shows proper class names via constructor.name.

Pull request overview

This PR consolidates data inspection functionality by extracting a reusable <DataInspector> component and improving class instance rendering. The changes replace direct ObjectInspector usage across multiple components with a unified component that provides consistent theming, custom type handling for StreamRef and ClassInstanceRef, and improved class name display in the inspector.

Changes:

• Created a new <DataInspector> component with custom node rendering and theme support
• Updated class instance hydration to use dynamically-named constructors for proper display
• Replaced all ObjectInspector usage across 5 components with the new DataInspector

Reviewed changes

[karthikscale3]

Tested it locally and everything looks good.

[TooTallNate]

Consolidate all ObjectInspector usage into a single DataInspector component
with shared theming, custom nodeRenderer for StreamRef/ClassInstanceRef, and
stream click context. Update all consumers (attribute-panel, events-list,
event-list-view, stream-viewer, conversation-view) to use DataInspector
instead of direct ObjectInspector or JSON.stringify. Fix class instance
hydration to create objects with dynamically-named constructors so
react-inspector shows proper class names via constructor.name.

Pull request overview

This PR consolidates data inspection functionality by extracting a reusable <DataInspector> component and improving class instance rendering. The changes replace direct ObjectInspector usage across multiple components with a unified component that provides consistent theming, custom type handling for StreamRef and ClassInstanceRef, and improved class name display in the inspector.

Changes:

• Created a new <DataInspector> component with custom node rendering and theme support
• Updated class instance hydration to use dynamically-named constructors for proper display
• Replaced all ObjectInspector usage across 5 components with the new DataInspector

[karthikscale3]

Tested it locally and everything looks good.

[TooTallNate]

Consolidate all ObjectInspector usage into a single DataInspector component
with shared theming, custom nodeRenderer for StreamRef/ClassInstanceRef, and
stream click context. Update all consumers (attribute-panel, events-list,
event-list-view, stream-viewer, conversation-view) to use DataInspector
instead of direct ObjectInspector or JSON.stringify. Fix class instance
hydration to create objects with dynamically-named constructors so
react-inspector shows proper class names via constructor.name.

Pull request overview

This PR consolidates data inspection functionality by extracting a reusable <DataInspector> component and improving class instance rendering. The changes replace direct ObjectInspector usage across multiple components with a unified component that provides consistent theming, custom type handling for StreamRef and ClassInstanceRef, and improved class name display in the inspector.

Changes:

• Created a new <DataInspector> component with custom node rendering and theme support
• Updated class instance hydration to use dynamically-named constructors for proper display
• Replaced all ObjectInspector usage across 5 components with the new DataInspector

Reviewed changes

Tested it locally and everything looks good.

[TooTallNate]

Consolidate all ObjectInspector usage into a single DataInspector component
with shared theming, custom nodeRenderer for StreamRef/ClassInstanceRef, and
stream click context. Update all consumers (attribute-panel, events-list,
event-list-view, stream-viewer, conversation-view) to use DataInspector
instead of direct ObjectInspector or JSON.stringify. Fix class instance
hydration to create objects with dynamically-named constructors so
react-inspector shows proper class names via constructor.name.

Pull request overview

This PR consolidates data inspection functionality by extracting a reusable <DataInspector> component and improving class instance rendering. The changes replace direct ObjectInspector usage across multiple components with a unified component that provides consistent theming, custom type handling for StreamRef and ClassInstanceRef, and improved class name display in the inspector.

Changes:

• Created a new <DataInspector> component with custom node rendering and theme support
• Updated class instance hydration to use dynamically-named constructors for proper display
• Replaced all ObjectInspector usage across 5 components with the new DataInspector

Tested it locally and everything looks good.

[TooTallNate]

Consolidate all ObjectInspector usage into a single DataInspector component
with shared theming, custom nodeRenderer for StreamRef/ClassInstanceRef, and
stream click context. Update all consumers (attribute-panel, events-list,
event-list-view, stream-viewer, conversation-view) to use DataInspector
instead of direct ObjectInspector or JSON.stringify. Fix class instance
hydration to create objects with dynamically-named constructors so
react-inspector shows proper class names via constructor.name.

Pull request overview

This PR consolidates data inspection functionality by extracting a reusable <DataInspector> component and improving class instance rendering. The changes replace direct ObjectInspector usage across multiple components with a unified component that provides consistent theming, custom type handling for StreamRef and ClassInstanceRef, and improved class name display in the inspector.

Changes:

• Created a new <DataInspector> component with custom node rendering and theme support
• Updated class instance hydration to use dynamically-named constructors for proper display
• Replaced all ObjectInspector usage across 5 components with the new DataInspector

Reviewed changes

Tested it locally and everything looks good.

[TooTallNate]

Consolidate all ObjectInspector usage into a single DataInspector component
with shared theming, custom nodeRenderer for StreamRef/ClassInstanceRef, and
stream click context. Update all consumers (attribute-panel, events-list,
event-list-view, stream-viewer, conversation-view) to use DataInspector
instead of direct ObjectInspector or JSON.stringify. Fix class instance
hydration to create objects with dynamically-named constructors so
react-inspector shows proper class names via constructor.name.

Pull request overview

This PR consolidates data inspection functionality by extracting a reusable <DataInspector> component and improving class instance rendering. The changes replace direct ObjectInspector usage across multiple components with a unified component that provides consistent theming, custom type handling for StreamRef and ClassInstanceRef, and improved class name display in the inspector.

Changes:

• Created a new <DataInspector> component with custom node rendering and theme support
• Updated class instance hydration to use dynamically-named constructors for proper display
• Replaced all ObjectInspector usage across 5 components with the new DataInspector

Tested it locally and everything looks good.

[TooTallNate]

Consolidate all ObjectInspector usage into a single DataInspector component
with shared theming, custom nodeRenderer for StreamRef/ClassInstanceRef, and
stream click context. Update all consumers (attribute-panel, events-list,
event-list-view, stream-viewer, conversation-view) to use DataInspector
instead of direct ObjectInspector or JSON.stringify. Fix class instance
hydration to create objects with dynamically-named constructors so
react-inspector shows proper class names via constructor.name.

Pull request overview

This PR consolidates data inspection functionality by extracting a reusable <DataInspector> component and improving class instance rendering. The changes replace direct ObjectInspector usage across multiple components with a unified component that provides consistent theming, custom type handling for StreamRef and ClassInstanceRef, and improved class name display in the inspector.

Changes:

• Created a new <DataInspector> component with custom node rendering and theme support
• Updated class instance hydration to use dynamically-named constructors for proper display
• Replaced all ObjectInspector usage across 5 components with the new DataInspector

Tested it locally and everything looks good.

[TooTallNate]

Consolidate all ObjectInspector usage into a single DataInspector component
with shared theming, custom nodeRenderer for StreamRef/ClassInstanceRef, and
stream click context. Update all consumers (attribute-panel, events-list,
event-list-view, stream-viewer, conversation-view) to use DataInspector
instead of direct ObjectInspector or JSON.stringify. Fix class instance
hydration to create objects with dynamically-named constructors so
react-inspector shows proper class names via constructor.name.

Pull request overview

This PR consolidates data inspection functionality by extracting a reusable <DataInspector> component and improving class instance rendering. The changes replace direct ObjectInspector usage across multiple components with a unified component that provides consistent theming, custom type handling for StreamRef and ClassInstanceRef, and improved class name display in the inspector.

Changes:

• Created a new <DataInspector> component with custom node rendering and theme support
• Updated class instance hydration to use dynamically-named constructors for proper display
• Replaced all ObjectInspector usage across 5 components with the new DataInspector
