Fix queued bubbles, queue persistence, duplicate confirm UX, semantic check

- Queued message bubbles now match user bubble style (primary colour,
  right-aligned, opacity 0.45) in both ChatView and WorkspaceView
- Queue persisted to localStorage (fa_conv_queue_<id>); survives page
  refresh, restored on fetchConversation, cleared on delete
- ToolCallCard confirm/deny: buttons now inline in header row; "Create
  anyway" calls POST /api/notes or /api/tasks directly (no LLM round-trip);
  shows "✓ Created" / "Skipped" state; removed chatStore dependency
- POST /api/notes and POST /api/tasks now accept project (name string) and
  resolve to project_id server-side, matching tools.py behaviour
- Remove semantic similarity duplicate check from create_note and
  create_task — 0.87 threshold was too aggressive for topically-related
  notes; title-based exact/fuzzy checks are sufficient
