chore: add environment configuration

- Configure Supabase ports to avoid conflicts (544xx range)
- Enable GitHub OAuth provider in Supabase config
- Add .env.example files for web and worker apps
- Fix .gitignore to track .env.example files

Local Supabase URLs:
- API: http://127.0.0.1:54421
- Studio: http://127.0.0.1:54423
- DB: postgresql://postgres:postgres@127.0.0.1:54422/postgres
