fix(app): enable remote session auto-accept

[Hona]

Summary

• register context-sensitive Settings commands in active routes so remote session dialogs inherit the correct SDK, sync, and model contexts
• retain one permission state and event listener per configured server, allowing unfocused server sessions to auto-accept requests without cross-server routing
• bind inactive-tab reads and asynchronous prompt submission to explicit server state, and preserve root-session overrides for child permissions
• add deterministic two-server SSE coverage for focused settings, background root/child responses, response host, session, and directory

Testing

• bun run test:e2e e2e/regression/remote-session-settings.spec.ts e2e/regression/remote-tab-busy.spec.ts
• bun test --preload ./happydom.ts ./src/context/permission-auto-respond.test.ts ./src/components/prompt-input/submit.test.ts
• bun typecheck
• bun run typecheck:e2e
• bun run test:browser
• pre-push full workspace typecheck (30 packages)
• detached pre-fix regression validation: background auto-accept test fails with no response before the retained-state fix

Pull request overview

This PR fixes remote-session “auto-accept permissions” configuration by ensuring the Settings command (and resulting dialog) is registered within the active server/session route context, so the dialog inherits the correct server-scoped providers (notably ServerSync/Permission).

Changes:

• Move Settings command registration out of the global new-layout shell and into the active routes (home, new-session, target session) so dialogs inherit correct server context.
• Keep remote session settings under the session-scoped PermissionProvider (including when the session route is rendering error fallbacks).
• Add an E2E regression test verifying auto-accept can be toggled for a session on a remote server.

File	Description
packages/app/src/pages/session.tsx	Wrap target session route in PermissionProvider and register settings command within that provider scope for correct server/session context.
packages/app/src/pages/new-session.tsx	Register the Settings command on the new-session route so the dialog is available with correct route context.
packages/app/src/pages/layout-new.tsx	Remove global Settings command registration from the new-layout shell.
packages/app/src/pages/home.tsx	Switch to useSettingsCommand() so the Settings command is registered (and an open callback is available) in the home route context.
packages/app/e2e/regression/remote-tab-busy.spec.ts	Add a regression test ensuring remote-session auto-accept can be enabled via the Settings dialog.
