Fix OpenCloud user/group management for OIDC authentication

Problem: Users routed to /login page instead of OIDC redirect.
Root cause: ConfigMap still configured for LDAP-based user/group management.

Changes:
- Users service: Changed driver from 'ldap' to 'owncloudsql'
- Groups service: Changed driver from 'ldap' to 'owncloudsql'
- Graph service: Removed LDAP identity backend configuration
- Auth services: Removed auth_basic LDAP provider (OIDC only)
- Commented out IDP/IDM service configs (excluded services)

Result: OpenCloud will use owncloudsql driver for OIDC-based auto-provisioning.
