fix: allow null values for Jitsi fields in AppointmentRequest

Add `null=True` to `jitsi_meet_url` and `jitsi_room_id` fields in the AppointmentRequest model. This allows these optional fields to be NULL at the database level in addition to accepting blank values, which is the proper Django pattern for optional string-based fields.

This change requires a database migration to be generated and applied.
