feat: improve ICS calendar sync UX and fix room URL matching

- Replace "Test Connection" button with "Force Sync" button (Edit Room only)
- Show detailed sync results: total events downloaded vs room matches
- Remove emoticons and auto-hide timeout for cleaner UX
- Fix room URL matching to use UI_BASE_URL instead of BASE_URL
- Replace FaSync icon with LuRefreshCw for consistency
- Clear sync results when dialog closes or Force Sync pressed
- Update tests to reflect UI_BASE_URL change and exact URL matching
