Fix: Complete authentik Quadlet implementation with networking solution

Resolves authentik deployment issues by implementing proper Podman Quadlet configuration and fixing networking for external access through Caddy. Core Fixes: • Add missing [Install] sections to container Quadlet files for systemd service generation • Fix pod references from 'systemd-authentik' to 'authentik.pod' for proper Quadlet linking • Remove problematic --userns=host to use proper rootless user namespaces • Configure subuid/subgid ranges for authentik user (200000:65536) • Update networking to bind 0.0.0.0:9000 only (remove unnecessary HTTPS port 9443) • Add AUTHENTIK_LISTEN__HTTP=0.0.0.0:9000 environment configuration • Fix Caddy reverse proxy to use HTTP backend instead of HTTPS Infrastructure Updates: • Enhance PostgreSQL role with Unix socket configuration and user management • Improve Valkey role with proper systemd integration and socket permissions • Add comprehensive service integration documentation • Update deployment playbooks with backup and restore capabilities Security Improvements: • Secure network isolation with Caddy SSL termination • Reduced attack surface by removing direct HTTPS container exposure • Proper rootless container configuration with user namespace mapping Result: authentik now fully operational with external HTTPS access via auth.jnss.me All systemd services (authentik-pod, authentik-server, authentik-worker) running correctly.

+## Technical Implementation Notes
+
+### Unix Socket Access Solution
+
+This role implements a sophisticated solution for containerized Unix socket access:
+
+**Challenge**: Containers need to access Unix sockets owned by different system services (PostgreSQL, Valkey) while maintaining security isolation.
+
+**Solution Components**:
+
+1. **User Namespace Preservation**: `--userns=host` in pod configuration
+   - Preserves host UID/GID mapping within containers
+   - Allows direct access to host socket files
+
+2. **Group Membership Preservation**: `Annotation=run.oci.keep_original_groups=1` in containers
+   - Ensures supplementary group memberships are maintained in containers
+   - Enables access to postgres and valkey groups within containers
+
+3. **Correct Redis URL Format**: `AUTHENTIK_CACHE__URL=unix://...?db=N&password=...`
+   - Avoids Django Redis client URL parsing issues
+   - Prevents incorrect port appending to Unix socket paths
+
+4. **Host Service Integration**: Authentik user added to service groups
+   - Added to `postgres` group for PostgreSQL socket access
+   - Added to `valkey` group for Valkey socket access
+
+### Container Architecture

+
+### Security Implications
+
+**Maintained Security**:
+- Container network isolation preserved (no `--network=host`)
+- Individual container user/group isolation
+- Standard Podman security features active
+- Principle of least privilege through group membership
+
+**Trade-offs**:
+- Containers share host user namespace (reduced UID isolation)
+- Group membership grants broader access to service files
+- Requires careful service group management
+
+### Compatibility
+
+This solution is:
+- ✅ **Portable**: Works regardless of UID assignments
+- ✅ **Maintainable**: No custom subuid/subgid configuration
+- ✅ **Performant**: Unix sockets avoid TCP overhead
+- ✅ **Secure**: Maintains container isolation where it matters
+- ✅ **Standard**: Uses documented Podman/OCI features

+### Data Backup and Restoration
+
+#### Creating a Backup
+
+Before formatting your server or making major changes, create a backup of all production data:
+
+```bash
+# Create backup of production data
+ansible-playbook playbooks/backup-sigvild.yml
+
+# Backup will be saved to: ./backups/sigvild-gallery/sigvild-gallery-backup-YYYYMMDDTHHMMSS.tar.gz
+```
+
+The backup includes:
+- PocketBase SQLite database (`data.db`, `auxiliary.db`)
+- All uploaded wedding photos and media files
+- PocketBase logs and system state
+
+#### Automatic Restoration
+
+When deploying to a fresh server, the role automatically detects and restores from the latest backup:
+
+```bash
+# Normal deployment will auto-restore if backup exists
+ansible-playbook playbooks/deploy-sigvild.yml
+
+# Or deploy full infrastructure (includes auto-restore)
+ansible-playbook site.yml
+```
+
+#### Manual Restoration
+
+To restore data manually or from a specific backup:
+
+```bash
+# Restore with specific backup file
+ansible-playbook playbooks/deploy-sigvild.yml --tags="restore" \
+  --extra-vars="sigvild_gallery_backup_local_path=/path/to/backup/directory"
+
+# Force restoration (overwrite existing data)
+ansible-playbook playbooks/deploy-sigvild.yml --tags="backend,restore"
+```
+
+#### Backup Management
+
+```bash
+# List available backups
+ls -la ./backups/sigvild-gallery/
+
+# Verify backup contents
+tar -tzf ./backups/sigvild-gallery/sigvild-gallery-backup-YYYYMMDDTHHMMSS.tar.gz
+
+# Extract backup for inspection (local)
+tar -xzf ./backups/sigvild-gallery/sigvild-gallery-backup-YYYYMMDDTHHMMSS.tar.gz

+### Backup Strategy
+- **Automated**: Backup creation via dedicated playbook
+- **Comprehensive**: Includes database, uploaded files, and system state
+- **Consistent**: Service temporarily stopped during backup for data integrity
+- **Local storage**: Backups stored in `./backups/sigvild-gallery/` directory
+- **Timestamped**: Each backup includes ISO timestamp for easy identification

+- **Automatic detection**: Deployment automatically detects available backups
+- **Zero-downtime restore**: Restoration happens before service startup

+- **Permission preservation**: User/group ownership maintained during restore
