feat(build): add Makefile for frontend application management

This commit introduces a Makefile for the frontend application that:
- Provides commands to start the app in background or foreground
- Includes utilities to check status and stop the application
- Reads environment variables from .env file with fallback values
- Sets up logging infrastructure with timestamped log files
- Includes help documentation for all available commands
