logistics router gains three procedures for the Visas tab:
- listVisaApplications: program-scoped, joined with project + attendee,
sorted by status priority (REQUESTED first → NOT_NEEDED last).
- updateVisaApplication: partial update of status / dates / nationality /
notes; clears nullable fields on null. Audit-logged as VISA_UPDATE
with previous + next snapshots.
- setVisaVisibility: flips Program.visaStatusVisibleToMembers. Audit-
logged as VISA_VISIBILITY_SET.
