Fixed email FROM address formatting that was breaking Django's email parser.
The display name contained an '@' symbol which violated RFC 5322 format.
Changes:
- Fix Authentik email FROM address (remove @ from display name)
- Add Mailgun SMTP credential cleanup on server destruction
- Fix Mailgun delete task to use EU API endpoint
- Add cleanup playbook for graceful resource removal
This ensures:
✓ Recovery emails work immediately on new deployments
✓ SMTP credentials are automatically cleaned up when destroying servers
✓ Email configuration works correctly across all environments

Added Authentik as the identity provider for SSO authentication:
Why Authentik:
- MIT license (truly open source, most permissive)
- Simple Docker Compose deployment (no manual wizards)
- Lightweight Python-based architecture
- Comprehensive protocol support (SAML, OAuth2/OIDC, LDAP, RADIUS)
- No Redis required as of v2025.10 (all caching in PostgreSQL)
- Active development and strong community
Implementation:
- Created complete Authentik Ansible role
- Docker Compose with server + worker architecture
- PostgreSQL 16 database backend
- Traefik integration with Let's Encrypt SSL
- Bootstrap tasks for initial setup guidance
- Health checks and proper service dependencies
Architecture decisions updated:
- Documented comparison: Authentik vs Zitadel vs Keycloak
- Explained Zitadel removal (FirstInstance bugs)
- Added deployment example and configuration notes
Next steps:
- Update documentation (PROJECT_REFERENCE.md, README.md)
- Create Authentik agent configuration
- Add secrets template
- Test deployment on test server
