5.1: Toolbar already has PluginToolbar with navigation, view mode, actions — no changes needed
5.2: Calendar visibility toggle fix:
- calendarStore.setCalendars now initializes visibleCalendarIds with all calendar IDs
- CalendarTree.tsx visibility check simplified to visibleCalendarIds.has(cal.id)
- No more empty-set-means-all-visible confusion
tsc clean
Replace direct {error} JSX rendering with typeof check + .message fallback.
When error is an object (not a string), React showed [object Object].
Now renders error.message or fallback string.
Standalone buttons:
- Add ExternalLink button to Dms, Calendar, Mail, ContactsList toolbars
- Create standalone pages for each (no sidebar, full screen)
- Add standalone routes outside ProtectedRoute
Window system for modals:
- AppointmentModal -> AppointmentEditForm + openWindow()
- ComposeModal -> MailComposeForm + openWindow()
- FilePreviewModal -> FilePreviewContent + openWindow()
- Calendar, Mail, Dms use openWindow() instead of modal state
- Migrated AppointmentModal from useState to React Hook Form + Zod
- Zod schema: title (required), calendar_id (required), start_at/end_at (required, end > start)
- Object-level superRefine for date validation (end must be after start)
- Error display via Input error prop and summary error div
- Preserved all existing functionality: create, edit, delete, prefill
- Added 3 validation tests (empty title, end before start, valid submit)
