Fix#1 - SECRET_KEY startup validation (config.py, .env):
- App refuses to start if SECRET_KEY is missing, shorter than 32 chars,
or matches a known insecure default value
- .env: replaced hardcoded test key with placeholder + generation hint
Fix#2 - Docker socket proxy (docker-compose.yml):
- Add tecnativa/docker-socket-proxy sidecar
- Only expose required Docker API endpoints (CONTAINERS, IMAGES,
NETWORKS, POST, EXEC); dangerous endpoints explicitly blocked
- Remove direct /var/run/docker.sock mount from main container
- Route Docker API via DOCKER_HOST=tcp://docker-socket-proxy:2375
Fix#3 - Azure AD group whitelist (auth.py, models.py, validators.py):
- New azure_allowed_group_id field in SystemConfig
- After token exchange, verify group membership via Graph API /me/memberOf
- Deny login with HTTP 403 if user is not in the required group
- New Azure AD users now get role 'viewer' instead of 'admin'
Fix#4 - Rate limiting on login (main.py, auth.py, requirements.txt):
- Add slowapi==0.1.9 dependency
- Initialize SlowAPI limiter in main.py with 429 exception handler
- Apply 10 requests/minute limit per IP on /login and /mfa/verify
- Multi-language support (EN/DE) with i18n engine and language files
- Configurable branding (name, subtitle, logo) in Settings
- Global default language and per-user language preference
- User management router with CRUD endpoints
- Customer status sync on start/stop/restart
- Health check fixes: derive status from container state, remove broken wget healthcheck
- Caddy reverse proxy and dashboard env templates for customer stacks
- Updated README with real hardware specs, prerequisites, and new features
- Removed .claude settings (JWT tokens) and build artifacts from tracking
- Updated .gitignore for .claude/ and Windows artifacts
