Refactor API endpoints for consistency and clarity

- Updated route paths for hackathon submissions, notifications, registrations, and teams to include more descriptive actions (e.g., "update", "create", "delete").
- Removed deprecated routes and adjusted corresponding test cases to reflect new endpoint structures.
- Enhanced test scripts to ensure compatibility with updated API routes and improved error handling for OTP resend functionality.
- Adjusted server startup script for better Windows compatibility and streamlined process management.
