feat(frontend): UX review followups — primitives + a11y/UX fixes across 4 passes

Browse Source 
New shared primitives:
- Toaster + toast-store, ConfirmSheet, Modal, focusTrap action,
  pullToRefresh action, avatarPalette + initials helper, Skeleton,
  HeartBurst, haptics, export-status store with onClearAuth hook

Critical UX/a11y:
- Replaced window.confirm with branded ConfirmSheet
- Focus management + Escape on every modal (PIN, Lightbox,
  Onboarding, ContextSheet, data-mode sheet, leave-confirm,
  HTML guide, host/admin ban + PIN-display modals)
- Sheet backdrops are real buttons with aria-label
- Silent ApiError catches now surface via global Toaster

Major polish:
- Dark-mode parity on HashtagChips + avatars (shared palette)
- Conditional Export tab in BottomNav (badge dot when ZIP ready)
- Back chevrons on /recover (history-aware) and /export
- Upload composer discard confirmation when content is staged
- Camera segmented Photo/Video shutter
- PIN auto-submit on 4th digit, paste-flash-free (controlled input)
- Welcome-back toast on /feed after PIN recovery

Minor:
- Skeleton states on feed; pull-to-refresh with live drag indicator
- Haptics on like / capture / submit / PIN-copy / onboarding complete
- Comment 500-char counter; quota "Fast voll" / "Limit erreicht" labels
- Onboarding pip ≥24px tap targets; long-press hint step
- overscroll-behavior lock on <html> while feed mounted
- teardownExportStatus wired via onClearAuth (covers 401 + explicit logout)
- ConfirmSheet per-instance titleId; Modal requires titleId or ariaLabel

Tests (7 new Playwright specs):
- 01-auth/pin-auto-submit, 01-auth/back-chevron
- 03-feed/confirm-sheet-delete, 03-feed/toast-on-failure
- 09-mobile/focus-trap, 09-mobile/sheet-escape,
  09-mobile/upload-cancel-confirm

FOLLOWUPS.md captures the deferred AT inert containment work
with acceptance criteria + implementation sketches.
