fix: accurate port banner and tkinter graceful fallback

- Move startup banner into main.py so it shows the actual configured
  port instead of a hardcoded 8080 in the launcher scripts
- Wrap tkinter import in try/except so embedded Python (which lacks
  tkinter) logs a warning instead of crashing the overlay thread
