Addresses review feedback: granting ALL PRIVILEGES on *.* is overly broad,
especially against a shared DB instance. A database-level grant on the
`romm\_test%` wildcard pattern still lets the user CREATE the per-worker
databases (romm_test_gw0, ...) needed by pytest-xdist, while confining it to
that namespace — verified that out-of-namespace CREATE DATABASE is denied.
PostgreSQL needs no equivalent change: its CI service user (POSTGRES_USER)
is the container superuser.

Add pytest-xdist and run the backend test suite across multiple workers
(`-n 4` in CI). Each worker gets its own database so the autouse
`clear_database` fixture can't wipe rows another worker is mid-test with:
- Rootdir `backend/conftest.py` sets a per-worker `DB_NAME`
(`romm_test_gw0`, ...) before any app module is imported, so each
worker's engine binds to its own database.
- `tests/conftest.py` creates the per-worker database on demand (mariadb/
mysql and postgresql paths) just before migrations run.
- The test user's grant is widened to `*.*` (setup.sql + CI) so it can
`CREATE DATABASE` for the workers.
