[Verify+Complaints] Facility document review + facility complaints; card location line

Card: move location to its own line above the date in the shift card (job card already did). Verification workflow: employers upload documents (license/permit) on a new Employer/Verify page; uploading marks the facility Pending. Admins see pending facilities with their documents on Admin/Facilities, can download each doc, and approve (تأیید شد) or reject with a reason. Documents stored as bytea in the DB (survives deploys via the existing volume); served only to the owner or an admin via /facility-doc/{id}. Facility model gains Verification status enum + note + requested-at; IsVerified kept in sync. Complaints: registered users/visitors can file a شکایت about a facility from shift/job detail pages (targets ReportTargetType.Facility, surfaces in Admin/Reports as مرکز). Migration backfills existing verified facilities to Verified.
