feat: implement Inbox view with triage actions

- Add InboxItem types and TriageAction/DeferDuration types
- Create Inbox component with:
  - Accept/Defer/Archive actions for each item
  - Keyboard shortcuts (A/D/X) for fast triage
  - Defer duration picker popup
  - Inbox Zero celebration state
  - Type-specific badges with colors
- Add comprehensive tests for all functionality

Closes bd-qvc
