chore(backups): add admin-only seed dumps (علی محقق)

Replaces the removed mock-data snapshots with minimal recovery seeds
that provision exactly one super user:

- casdoor.dump: full casdoor schema + built-in console admin (admin/123),
  org 'inventory', app 'inventory-app', the JWT signing cert, and the
  single org user ali.mohaghegh (علی محقق, plain password) — tokens,
  sessions and records cleared.
- procurement.dump: full procurement schema + the single users row
  (علی محقق, role=admin) linked by casdoor_id — all other tables empty;
  init_db re-seeds categories/units at startup.

Login: ali.mohaghegh (Casdoor rejects spaces in usernames, so the
spaceful 'ali mohaghegh' is not a valid login name).

Restore on a fresh volume with:
  docker compose stop api casdoor
  docker cp 'backups/علی محقق/casdoor.dump' procurement-postgres:/tmp/
  docker cp 'backups/علی محقق/procurement.dump' procurement-postgres:/tmp/
  docker exec procurement-postgres pg_restore -U postgres -d casdoor --clean --if-exists /tmp/casdoor.dump
  docker exec procurement-postgres pg_restore -U postgres -d procurement --clean --if-exists /tmp/procurement.dump
  docker compose start casdoor api

Both dumps were round-trip validated (pg_restore into scratch DBs:
casdoor = 2 users / 2 orgs / 2 apps / 1 cert; procurement = 1 admin user,
all other tables empty).
