Fix OpenCloud internal authentication with auto-initialization

- Removed read-only ConfigMap mount that prevented initialization
- Added 'opencloud init' to startup command to auto-generate config
- Config is now generated in /etc/opencloud at container startup
- Admin user is automatically created with random password
- Service users are created by init process
- Fixes HTTP 500 error on login

This allows OpenCloud to properly initialize its internal IDM/IDP
services with the necessary service users for inter-service auth.
