- Change database.username from "hades_user" to "mysql_user" to match
the shared MySQL user created by Backstage environment provisioning
- Remove mysql.enabled=true condition from dbinit job so SQL migrations
run against external/shared MySQL databases too
Without these fixes, deploying hades with mysql.enabled=false (Backstage
shared MySQL) causes access denied because hades_user doesn't exist in
the shared MySQL, and dbinit is skipped so no tables are created.
