OnPostPublishAsync inserted a Shift/Job with FacilityId=0 when no
facility was selected (e.g. the dropdown is empty because no facilities
exist yet), throwing FK_Shifts_Facilities_FacilityId and surfacing the
production error page.
- Resolve-or-create the facility before insert: use the picked one, else
create an unverified Facility from a typed name (reusing same-named).
- Guard the role too; on missing facility/role redirect back with a
Persian error message instead of 500.
- Review form: add "new facility name" input + "— none —" option +
error alert; add .alert-error style.
