fix: apply local patches for self-hosted dev environment

- Caddyfile: add security headers, X-Forwarded-For, serve app from static files
- compose: add FLUXER_API_PUBLIC_ENDPOINT for admin service
- rate limits: relax auth register/login for dev (50/60s)
- rspack: read CDN_ENDPOINT from env instead of hardcoded fluxerstatic.com
- gitignore: add dev/secret.txt
- add dev/livekit.yaml for local LiveKit config
