Breaking changes

Requires HA 2024.11.0 or later
fault codes have been moved from primary entities into the problem binary_sensor for many devices.
Some timer entity names have standardised. Migration should take care of keeping history intact and avoid zombie entities, but any references in automations, scripts or manual config may need updating.

Many devices: standardize problem binary_sensors to contain fault code, where fault code was on primary entity, it has moved.
