Remove Bitwarden authelia middleware and simplify networks

- Remove authelia middleware from Vaultwarden (Bitwarden) for app compatibility
- Simplify all compose files to use only homelab-network and traefik-network
- Remove unnecessary isolated networks (nextcloud-network, wordpress-network, etc.)
- Remove monitoring-network, formio-network, and media-network
- All services now communicate through the unified homelab-network
- Maintain traefik-network for proxied services only
