feat: topbar quick capture, fix mobile bottom nav and more panel

- Add quick capture input to topbar (desktop: inline 250px, mobile: full-width
  with submit button) that POSTs to /capture/add with redirect back to current page
- Fix mobile bottom bar: 5 items (Dashboard, Focus, Tasks, Capture, More),
  nowrap/overflow:hidden to prevent multi-line wrapping
- Rebuild mobile More panel as 3-column grid overlay (z-index 998/999/1000 stack)
  with backdrop dismiss, 8 items: Calendar, Notes, Meetings, Decisions, Contacts,
  Processes, Weblinks, Admin
- Add file seed fixture and registry mapping to eliminate 4 test skips
- Add time_budgets form factory patterns to fix 2 test failures
