feat(postgres): add split_postgres_connections filter and average pool fact

Browse Source 
Compute POSTGRES_ALLOWED_AVG_CONNECTIONS once and propagate to app roles (gitlab, mastodon, listmonk, matrix, pretix, mobilizon, openproject, discourse). Fix docker-compose postgres command (-c flags split). Add unit tests. Minor env/locale tweaks and includes.
