fix: Correct reset consumable parameters for strainer and cleaning brush

[allenporter]

The vacuum firmware expects the parameter in the reset_consumable command to match the internal property keys exactly. For the dock strainer and cleaning brush, these keys are plural:

• strainer_work_times
• cleaning_brush_work_times

Currently, ConsumableAttribute defines them as singular (strainer_work_time and cleaning_brush_work_time). Because of this, the library sends singular parameters when resetting them, which the vacuum firmware silently ignores.

This PR:

1. Updates the values of ConsumableAttribute.STRAINER_WORK_TIME and ConsumableAttribute.CLEANING_BRUSH_WORK_TIME to their correct plural forms (strainer_work_times and cleaning_brush_work_times).
2. Corrects the unit tests and integration/simulator tests to expect and verify the correct plural parameters.
