Kevin Veen-Birkenbach af1ee64246 web-app-mediawiki: installer-driven bootstrap, DB readiness, idempotent admin; drop LocalSettings bind-mount
Tasks:
- Enable docker_compose_flush_handlers=true so services come up immediately.
- Add DB readiness guard via maintenance/sql.php (SELECT 1).
- Run maintenance/install.php on empty schema with robust changed_when/failed_when (merge stdout+stderr); keep secrets hidden.
- Run maintenance/update.php for migrations with neutral changed_when unless work is done.
- Make admin creation idempotent: tolerate 'already exists' and 'Account exists', keep async+no_log.

Config changes:
- Remove LocalSettings.php template and its host bind-mount from compose.
- Drop MediaWiki settings path variables and META namespace variable (unused after switch).

Result: First boot is fully automated (schema + admin), subsequent runs are cleanly idempotent.
