Add automatic plugin installation on first Docker deployment

- Add docker-entrypoint.sh: runs migrations and bootstraps plugins
- Add bootstrap-plugins.sh: installs all plugins (disabled by default)
- Update Dockerfile to use entrypoint
- Plugins can now be enabled via Settings UI after first deployment
- Idempotent: safe to run multiple times
- Solves issue where imported prod databases had tables but no plugin registry
