HA 2025.1 new vacuum STATE deprecation warnings due for removal in 2026.1

[AnthonyBe]

There are a lot of them so figured a generic issue to capture them all made most sense:

2025-01-07 20:59:29.909 WARNING (ImportExecutor_0) [homeassistant.components.vacuum] STATE_DOCKED was used from mydolphin_plus, this is a deprecated constant which will be removed in HA Core 2026.1.

2025-01-07 20:59:29.990 WARNING (ImportExecutor_0) [homeassistant.components.vacuum] STATE_ERROR was used from mydolphin_plus, this is a deprecated constant which will be removed in HA Core 2026.1.

2025-01-07 21:00:37.759 WARNING (MainThread) [homeassistant.helpers.frame] Detected that custom integration 'mydolphin_plus' is setting state directly. Entity vacuum.aquawize_aw6 (<class 'custom_components.mydolphin_plus.vacuum.MyDolphinPlusLightEntity'>) should implement the 'activity' property and return its state using the VacuumActivity enum at custom_components/mydolphin_plus/vacuum.py, line 102: self._attr_state = state. This will stop working in Home Assistant 2026.1, please create a bug report at https://github.com/sh00t2kill/dolphin-robot/issues
