Keep init but remove admin password creation

Problem: Removing init entirely broke OpenCloud - needs init for config setup.
Solution: Keep 'opencloud init' but remove '--admin-password' flag.

Changes:
- Restored 'opencloud init' command (needed for jwt_secret and config)
- Removed '--admin-password' flag (prevents local admin user creation)
- IDM_CREATE_DEMO_USERS=false still set (prevents demo users)

Result: Init runs to setup config, but no local users are created.
Only OIDC auto-provisioned users will exist.
