Activates the previously-disabled Visas tab on /admin/logistics.
VisasTab renders a flat table joined per attendee per project, sorted
by status priority. Status filter pills mirror the Confirmations tab.
The header carries a "Visible to teams" Switch backed by a new
logistics.getVisaVisibility query and the existing setVisaVisibility
mutation; toggling it controls whether members see their own status.
VisaEditDialog is a per-row editor with a status dropdown,
nationality input, three native date inputs (invitation / appointment
/ decision), and a notes textarea. No file uploads — the platform
deliberately holds zero document artifacts.

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.
