Shared MySQL (mysql-5-7) only has mysql_user. The hades app connects
as hades_user which doesn't exist. dbinit runs as root, so it can
create the user before migrations run.

- Moved helm/hades/* to hades/ to match ArgoCD path: hades
- Included mysql-1.6.9.tgz subchart for ArgoCD dependency resolution
- Fixed sync wave ordering: dbinit wave 0, deployment wave 1
