fix: resolve TypeScript typing issues across monorepo

- Add Jest type definitions to backend package
- Fix database package TypeScript build configuration to generate .d.ts files
- Add @nbw/database dependency to frontend package
- Fix incorrect import paths in frontend components
- Add missing @types/unidecode dependency to song package
- Improve build script with proper build order and error handling
- Update frontend tsconfig to use bundler module resolution

All packages now build successfully with proper type exports.
