Rename Projekt.ino to Projekt_Arduino.ino

- Rename the main sketch file and adjust references accordingly.
- Clean up Config.h spacing and delete unused turn‑signal constants.
- Remove direction‑related LCD character data and its update logic.

- Simplify display initialization and eliminate the old delay in the
  loop.
- Add serial debug output for the car enable state.
