Introduce typed token value objects (EventToken, OrganizerToken,
RsvpToken) and refactor all existing Event code to use them.
Add POST /events/{token}/rsvps endpoint that persists an RSVP and
returns an rsvpToken. Populate attendeeCount in GET /events/{token}
from a real count query instead of hardcoded 0.
Includes: OpenAPI spec, Liquibase migration (rsvps table with
ON DELETE CASCADE), domain model, hexagonal ports/adapters,
service layer, and full test coverage (unit + integration).

Domain: add timezone field to Event and CreateEventCommand.
Ports: new GetEventUseCase inbound port.
Service: implement getByEventToken, validate IANA timezone on create.
Controller: map to GetEventResponse, compute expired flag via Clock.
Persistence: timezone column in JPA entity and mapping.
Tests: integration tests use DTOs + ObjectMapper instead of inline JSON,
GET tests seed DB directly via JpaRepository for isolation.

Add Event entity, CreateEventCommand, ports (CreateEventUseCase,
EventRepository), and EventService with Clock injection for
deterministic testing. Expiry date must be in the future.
