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.

Password reset: multi-app support with custom notification linking to correct
frontend (app/portal/admin). Email change: self-service with password
confirmation and admin-initiated, both sending verification to new address
with 24h expiry. Confirmation sent to old email on completion. Password
change: authenticated endpoint revoking other sessions.
