feat: add user_id ticket support and public events endpoint

- Tickets can be created with user_id instead of name/email
- name/email default to empty string in DB (not NULL-safe)
- New endpoints: GET /api/v1/events/public, GET /api/v1/tickets/user/{user_id}
- POST /api/v1/tickets/{event_id} accepts user_id in body
- Migration m007 adds user_id column to tickets table
- CreateTicket validates: either user_id or (name + email) required
