feat(sprint7): Phase 2.5 — Club Event Calendar

- Flyway V14: club_events + event_rsvps tables with reminder_sent tracking
- Enums: EventType, RsvpStatus, RecurrenceRule + extend AuditEventType/NotificationType
- Entities: ClubEvent (extends AbstractTenantEntity), EventRsvp (unique event+member)
- Repositories: ClubEventRepository, EventRsvpRepository with date-range and status queries
- EventService: CRUD, RSVP with maxAttendees enforcement (409 if full), iCal RFC 5545 generation, recurring event virtual expansion, notifications on create/cancel, auto-post to Info Board
- EventReminderScheduler: hourly check, 24h reminder to ACCEPTED/MAYBE attendees
- EventController: admin CRUD (MANAGE_INFO_BOARD permission), portal upcoming events, RSVP endpoint, iCal download (text/calendar), attendee list
- Frontend: events.ts service (React Query hooks matching apiClient pattern), admin calendar page (month grid with event dots, create dialog, event cards), portal events page (RSVP buttons, capacity display)
- Navigation: added Kalender with Calendar icon
- i18n: events.* keys in de.json and en.json
- UI: added @radix-ui/react-switch + Switch component
