fix(slink,fleet): append APP_ENV/APP_SECRET to .env, use setup_mariadb_db

- slink: APP_ENV and APP_SECRET not present in .env.example, sed patterns
  never matched → Symfony defaulted to dev mode → WebProfilerBundle crash
  (not installed with --no-dev). Now appends APP_ENV=prod + APP_SECRET.
- fleet: use setup_mariadb_db helper instead of manual SQL, reference
  MARIADB_DB_PASS, depend on mariadb.service
