feat: enhance deployment process and server configuration

- Updated `deno.json` to allow environment variable access in the start task.
- Added `deploy.sh` script for building and deploying the application to a remote server.
- Modified `main.ts` to retrieve the `AUTH_SECRET` and `PORT` from environment variables.
- Created `my-score.service` for managing the Deno service with systemd.
- Cleaned up `user.ts` by removing unnecessary console logs.
