Errors are being redireceted to /dev/null about picosnitch

Thank you!

The command picosnitch dash is intended to be more "user friendly" and completely detach itself from the terminal, but I agree showing the errors would be helpful. There is also the currently undocumented command picosnitch start-dash which does not detach itself nor pipe to /dev/null.

Maybe when dash launches, the below print statement could also suggest trying start-dash to see any error messages if dash fails to open.

picosnitch/picosnitch.py

Lines 2326 to 2330 in 34f9f1f

	except Exception:
	pass
	print(f"serving web gui on http://{os.getenv('HOST', 'localhost')}:{os.getenv('PORT', '5100')}")
	if sys.executable.startswith("/snap/") or sys.executable.startswith("/nix/"):
	subprocess.Popen(["bash", "-c", f'/usr/bin/env python3 -m webbrowser -t http://{os.getenv("HOST", "localhost")}:{os.getenv("PORT", "5100")}'], stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL)

It is also probably worth mentioning the DASH_DEBUG environment variable which enables the dash dev tools when true.

The same also goes for picosnitch start and picosnitch start-no-daemon (but this is already the command systemd uses so you'd see the errors in journalctl).
