Update fake-indexeddb dependency to version 6.2.5 in package.json and yarn.lock

- Introduced `npm-run-all` for improved script management in package.json.
- Updated Vite configuration to include test settings for both browser and Node environments.
- Added integration tests for API CRUD operations, including budget and category management.
- Created setup files for browser and Node testing environments.
- Updated yarn.lock to include new dependencies.

This commit enhances the testing framework and ensures better compatibility across environments.
