Update Docker configurations for balanced security and functionality

- Simplify daemon.json to minimal working version, removing problematic
  security settings that caused read-only filesystem issues
- Update Gitea docker-compose.yml to working configuration:
  - Remove read-only filesystem (breaks s6-overlay init)
  - Keep user privilege dropping via USER_UID/USER_GID
  - Bind SSH port directly for Git operations
  - Maintain localhost binding for web interface
