fix: resolve admin white screen via static ChatWindowProvider import

- Statically declare ChatWindowProvider in payload.config.ts admin.components.providers
- Regenerate importMap.js with correct component mappings
- Update Dockerfile to support _at-mintel monorepo sync for local builds
- Add .gitignore entries for manual build artifacts
- Update blocks and collections (payload-ai integration updates)
- Sync pnpm-lock.yaml
