Fix wsssh-server Debian package dependencies

- Removed unnecessary Python package dependencies from debian/control
- Since wsssh-server uses PyInstaller standalone binary, it doesn't need:
  - python3-websockets
  - python3-flask
  - python3-flask-login
  - python3-flask-sqlalchemy
  - python3-pty
  - python3 (base Python is still needed for the binary to run)
- Kept only essential dependency: adduser (for user creation)
- Updated package description to clarify it's a standalone binary
- This resolves dpkg dependency issues when installing on remote machines
