feat(db-tool): expose overridable postgresql arg and PG_CONF_FILE env

Browse Source 
Wrap db-tool, postgres-init, postgres-cleanup with lib.makeOverridable so
consumers can inject extension-enabled PostgreSQL via .override { postgresql = ...; }.
Add PG_CONF_FILE: when set, replaces script-generated postgresql.conf entirely
(runtime port and unix_socket_directories still appended/overridden).
