feat: add "Lid toevoegen als deelnemer" shortcut for org members

Adds two new API endpoints to quickly add organisation members as event
persons with user_id pre-linked and status approved:
- GET /organisations/{org}/members/available-for-event/{event}
- POST /organisations/{org}/events/{event}/persons/from-member

Includes frontend dialog with member search, crowd type selection, and
click-to-add behavior in the Personen tab.
