Add a single source of truth in tests/e2e/helpers.py for the database
images and their in-container data dirs (POSTGRES_IMAGE=postgres:alpine,
POSTGRES_DATA_DIR=/var/lib/postgresql, MARIADB_IMAGE=mariadb:latest,
MARIADB_DATA_DIR=/var/lib/mysql) and route every test through it.
postgres:alpine now tracks 18+, which refuses a mount at
/var/lib/postgresql/data and stores data under /var/lib/postgresql, so
the mounts and the marker path move there. Drop the --rsync-image and the
renamed hard-restart flag from the invocations.

- add `make clean` and run it before `test-e2e` to avoid stale artifacts
- restore: do not hardcode `mysql` for --empty; use detected mariadb/mysql client
- e2e: improve subprocess error output for easier CI debugging
- e2e: adjust MariaDB readiness checks for socket-only root on MariaDB 11
- e2e: add `wait_for_mariadb_sql` and run SQL readiness checks for dedicated TCP user
- e2e: update MariaDB full/no-copy tests to use dedicated user over TCP and consistent credentials
