Fix the remaining TODO from 2e3b8e5: replace the TypeId(requestId.value) hack
with a proper requestId→sessionId mapping stored in ApprovalCoordinator and
populated when onApprovalRequested fires from the event store subscription.
Changes across the full bugfix batch (all 9 bugs from TUI rework):
- Bug 1: ApprovalCoordinator broadcasts non-null toolName/preview
- Bug 2: ApprovalDto carries toolName/preview for late-connected clients
- Bug 3: SessionEventBridge.replaySnapshot() preserves toolName/preview
- Bug 4: TUI SessionsReducer processes enriched ApprovalDto fields
- Bug 5: DomainEventMapper passes sessionSequence; GlobalStreamHandler
tracks per-session counters so live events aren't dropped
- Bug 6: KeyResolver restores Ctrl+L/E/C/N bindings
- Bug 7: SessionSnapshot carries workflowId for display names
- Bug 8: ↑↓ navigates selection only; Enter/sessionEntered gates IN_SESSION
- Bug 9: EventHistoryStrip capped at 4 lines to prevent overflow
- Bonus: ApprovalCoordinator.lookupSession() with proper requestId→sessionId mapping
