* fix: add FF_ENABLE_CALDAV feature flag for CalDAV functionality
Introduces a new dedicated feature flag for CalDAV sync that checks
both FF_ENABLE_CALDAV and CALDAV_ENABLED environment variables. This
allows the CalDAV tab to appear in profile settings when users set
CALDAV_ENABLED=true as documented.
The existing FF_ENABLE_CALENDAR remains unchanged as it's for a
separate (hidden) calendar feature.
Changes:
- Added 'caldav' feature flag to backend service (checks FF_ENABLE_CALDAV
or CALDAV_ENABLED)
- Updated frontend FeatureFlags interface to include 'caldav'
- Changed CalDAV tab to use 'caldav' feature flag instead of 'calendar'
- Added FF_ENABLE_CALDAV to .env.example, .env.test, Dockerfile, and CI
Fixes#1048

- frontend/components/Navbar.tsx
- frontend/components/Sidebar.tsx
- frontend/components/Sidebar/SidebarNav.tsx
