feat: Show next run time of state

[NiveditJain]

Display the scheduled enqueue time for nodes that have been signaled with `ReQueueAfterSignal` or `RequeueAtSignal` in the Node Details modal.

Motivation

When a node raises ReQueueAfterSignal or RequeueAtSignal, the state is scheduled to be enqueued at a future time. Currently, users cannot see when the node will be executed next from the dashboard, making it difficult to:

1. Monitor scheduled executions – Users need visibility into when delayed nodes will run
2. Debug timing issues – Understanding the scheduled time helps debug workflow timing problems
3. Plan workflow execution – Knowing when nodes will execute helps with workflow planning and coordination

Current State

What Exists

Component	Location	Purpose
ReQueueAfterSignal	python-sdk/exospherehost/signals.py	Relative delay requeue (timedelta)
RequeueAtSignal	python-sdk/exospherehost/signals.py	Absolute timestamp requeue (datetime)
enqueue_after field	state-manager/app/models/db/state.py	Unix timestamp (ms) when state should be enqueued
NodeDetailsModal	dashboard/src/components/NodeDetailsModal.tsx	Displays node information and status
NodeRunDetailsResponse	state-manager/app/models/node_run_details_models.py	API response model for node details

Current Limitations

• The enqueue_after field exists in the State model but is not exposed in the NodeRunDetailsResponse
• The dashboard Node Details modal does not display the next run time
• Users cannot see when a node scheduled for requeue will execute

Proposed Solution

Overview

Add the enqueue_after field to the node details API response and display it in the Node Details modal when:

• Node status is CREATED
• enqueue_after timestamp exists
• enqueue_after is in the future (greater than current time)

Key Features

1. API Enhancement – Include enqueue_after in NodeRunDetailsResponse
2. UI Display – Show "Next Run Time" in the Status & Timestamps section
3. Conditional Display – Only show when node is scheduled for future execution
4. User-Friendly Format – Display timestamp in user's local timezone and locale format
