collect: migrate from weconnect to CarConnectivity + VW connector

Replace the weconnect library with carconnectivity and
carconnectivity-connector-volkswagen.  The connector is configured via
a dict passed to CarConnectivity(); startup()/fetch_all() replace
login()/update().  All domain extractors in data_model.py are rewritten
for the new object model (vehicle.charging.*, vehicle.get_electric_drive(),
vehicle.climatization.*, etc.).  Remaining time fields are now derived
from estimated_date_reached DateAttributes.  Battery temperatures are
read directly in °C (no Kelvin conversion).  Auth error handling drops
the manual re-login since the connector manages token refresh internally.
