fix(app): --display CLI flag now takes priority over preset

Browse Source 
The --display CLI flag wasn't being checked, so it was always using
the preset's display backend.

Now app.py checks if --display was provided and uses it if present,
otherwise falls back to the preset's display setting.

Example:
  uv run mainline.py --preset border-test --display websocket
  # Now correctly uses websocket instead of terminal (border-test default)
