home-assistant: fix Jinja2 battery template syntax
All checks were successful

Browse Source 
The template used | min(100) | max(0) which is invalid Jinja2 syntax.
These filters expect iterables (lists), not scalar arguments. This
caused TypeError warnings on every MQTT message and left battery
sensors unavailable.

Fixed by using proper list-based min/max:
  [[[value, 100] | min, 0] | max
