feat(web): fold duplicates+inbox into /review; sidebar UX cleanup

- /duplicates and /inbox routes removed and folded into /review as
  additional tabs alongside cause tabs; /duplicates keeps a redirect
  for bookmarks.
- LeftSidebar: drop import/inbox tile and favorites; show per-user
  BasePath label at the folder root.
- RightSidebar: split file header into read-only path over editable
  basename (matches sidecar rename contract); date field switches to
  plain-text ISO YYYY-MM-DD (no native datetime picker) with strict
  validation and revert-on-invalid-blur; preserves original hour.
- BulkMetadataSidebar: same ISO-only date input with invalid-state
  styling and apply-button gating.
- BulkActionBar: drop redundant Restore and Undo buttons; ⌘Z still
  reachable via gridKeyNav.
- gridKeyNav: remove favorite toggle (F) alongside the favorites view
  retirement.
