Every module had buttons that rendered visually but did nothing when
clicked. Server actions existed for all of them. Created client
components with dialogs/forms and wired them in.
BOOKINGS MODULE:
- BookingStatusActions: Check-in/Check-out/Cancel buttons now call
updateBookingStatus server action with loading states + toast

name, capacity, price/night fields → calls createRoom
- CreateGuestDialog: 'Neuer Gast' opens dialog with first/last name,
email, phone fields → calls createGuest

dialog with participant data + DOB → calls registerForEvent
- CreateHolidayPassDialog: 'Neuer Ferienpass' opens dialog with name,

NEWSLETTER MODULE:

All dialogs use German labels, helpful placeholders, loading spinners,
toast notifications, and form validation appropriate for association
board members (Vereinsvorstände, 40-65, moderate tech skills).
The previous lint fix incorrectly renamed ctx to _ctx in server actions
that actually USE ctx.user.id for authorization. This caused runtime
'ctx is not defined' errors when creating pages, modules, etc.
Reverted all 13 action files back to using ctx properly.
