## Task X: Application Smoke Test — TEST: PASS
This task involves performing a smoke test to ensure the application builds, installs dependencies, and starts both backend and frontend servers without crashing.

### X.1 Project Setup Verification
- [x] Check project file structure using `tree -L 2` command to identify any missing files
- [z] Create any missing files found during structure check (e.g., notes_app_20251002_055810-notes_app_20251002_055810-f-f/authsec_angular/frontend/angular-clarity-master/src/reportWebVitals.js)

### X.2 Dependency Installation
- [x] Install missing dependencies for backend (e.g., mvn clean install, gradle build, pip install -r requirements.txt)
- [x] Install missing dependencies for frontend (e.g., npm install)

### X.3 Application Startup Verification
- [x] Start the backend server.
- [x] Start the frontend development server.
- [x] Verify that both processes start without crashing. If an error occurs, analyze the logs, create a new subtask to fix the bug, and re-run the smoke test until it passes.
