VAG Connect v2.20.1

Patch release — bugfixes only.

Fixed

• Škoda charge controls work again (#866). Setting the charge limit — plus battery-care, charging-current and auto-unlock alongside it — failed with a server error while the official app worked. They were sent as an action rather than a settings change (POST instead of PUT), so Škoda's backend rejected them. All four now use the exact request the app sends, checked against the actively-maintained Škoda library.
• Two-way controls no longer vanish on older Car-Net cars. On some legacy Car-Net vehicles the integration couldn't read the car's service directory (it came back "unauthorised"), and a v2.20.0 change then hid every lock / climate / charging control for the rest of the session. Now, when that directory can't be read, the controls stay available (a failed command is reported when you use it) instead of disappearing — while a car that genuinely proves it lacks a service still correctly hides it. That read is also retried once after refreshing the login.

Changed

• Internal tidy-up of out-of-date code comments from the v2.20.0 command-routing change. No behaviour change.

Thanks to @tader for the clean Škoda charge-limit report (#866).
