Critical fix for argon2 password hash preservation:
- Root cause: Bash variable expansion of $ characters in argon2id hashes
- Solution: Write hash directly from Docker output to file, bypass bash variables entirely
- setup-homelab.sh: Stream Docker output directly to /tmp/authelia_password_hash.tmp
- deploy-homelab.sh: Read hash file in Python to avoid any bash expansion
- Result: Password hash correctly preserved with full $argon2id$v=19$m=... format
Other changes:
- Added DOCKER_API_VERSION=1.44 env var for watchtower (API compatibility)
- Watchtower still has issues with Docker 29.1.4 - keeping version pinned for investigation
Tested on Debian 12 with Docker 29.1.4:
✅ All 11 critical containers healthy
✅ Authelia authentication working correctly
✅ Password hash preserved through entire deployment workflow
⚠️ Watchtower restart loop (non-critical, under investigation)
