teernisse b9c1bd6ff1 feat(dashboard): improve real-time updates and scroll behavior
Major UX improvements to conversation display and state management.

Scroll behavior (SessionCard.js):
- Replace scroll-position tracking with wheel-event intent detection
- Accumulate scroll-up distance before disabling sticky mode (50px threshold)
- Re-enable sticky on scroll-down when near bottom (100px threshold)
- Always scroll to bottom on first load or user's own message submission
- Use requestAnimationFrame for smooth scroll positioning

Optimistic updates (App.js):
- Immediately show user messages before API confirmation
- Remove optimistic message on send failure
- Eliminates perceived latency when sending responses

Error tracking integration (App.js):
- Wire up trackError/clearErrorCount for API operations
- Track: state fetch, conversation fetch, respond, dismiss, SSE init/parse
- Clear error counts on successful operations
- Clear SSE event cache on reconnect to force refresh

Conversation management (App.js):
- Use mtime_ns (preferred) or last_event_at for change detection
- Clean up conversation cache when sessions are dismissed
- Add modalSessionRef for stable reference across renders

Message stability (ChatMessages.js):
- Prefer server-assigned message IDs for React keys
- Fallback to role+timestamp+index for legacy messages

Input UX (SimpleInput.js):
- Auto-refocus textarea after successful submission
- Use setTimeout to ensure React has re-rendered first

Sorting simplification (status.js):
- Remove status-based group/session reordering
- Return groups in API order (server handles sorting)
