Set MS_WORKERS=1, MS_ENABLE_IPV6=false, and MS_WEBRTC_LISTEN_IPS to announce only EXTERNAL_IPv4 for webrtc-sfu. Helps avoid mediasoup router init issues seen when IPv6 is present.

Context: debugging mediasoup/WebRTC failures caused by empty/interpolated vars (EXTERNAL_IPv4, etc.).
- Normalize config/main.yml (ip6_enabled flag, enable greenlight/coturn) and tidy formatting.
- Extend vars/main.yml with BBB_* switches (IPv6, Greenlight, Coturn), TURN/Coturn cert paths.
- env.j2: wire secrets & toggles, guard IPv6 via BBB_IP6_ENABLED, switch LDAP/OIDC to role flags, add TURN/STUN, and general cleanup.
- tasks/main.yml: use BBB_* fact names, robust path joins, write docker-compose.override.yml, and notify compose on env/override changes.
- tasks/01_docker-compose.yml: reference new BBB_DOCKER_COMPOSE_* facts.
- Add templates/docker-compose.override.yml.j2 (placeholder for SFU overrides to avoid bad defaults during runs).
Rationale: make Compose brings deterministic (no empty ), paving the way to set MS_WEBRTC_LISTEN_IPS in override without risk.

- Converted group_vars/all/13_ldap.yml from lower-case to ALL-CAPS nested keys.
- Updated all roles, tasks, templates, and filter_plugins to reference LDAP.* instead of ldap.*.
- Fixed Keycloak JSON templates to properly quote Jinja variables.
- Adjusted svc-db-openldap filter plugins and unit tests to handle new LDAP structure.
- Updated integration test to only check uniqueness of TOP-LEVEL ALL-CAPS constants, ignoring nested keys.
