Implement ConfigMap mount with init container for envsubst

Added init-config container that:
- Uses alpine with envsubst to expand environment variables
- Reads ConfigMap template from /etc/opencloud-template
- Writes expanded config to emptyDir at /etc/opencloud-processed
- Main container mounts processed config at /etc/opencloud

Simplified ConfigMap to only essential LDAP configuration:
- Graph service LDAP (external OpenLDAP)
- Users/Groups service LDAP configuration
- Removed default values (env vars override anyway)
- Only  placeholder remains

This follows OpenCloud's config precedence:
1. opencloud.yaml (base config)
2. Environment variables (highest precedence)
