HealthConnect Sensors (not!) showing with correct category

**Home Assistant Android app version(s):**
2025.5.3-full

**Android version(s):**
15

**Device model(s):**
Pixel 8

**Home Assistant version:**
2024.10, but the version is irrelevant here

**Last working Home Assistant release (if known):**
new feature in app

**Description of problem, include YAML if issue is related to notifications:**
the newest version of the HASS app supports HealthConnect Sensors. But it looks like all sensor entities created from HealthConnect appear as "diagnostic" sensor. This is clearly wrong, as diagnostic sensors are meant to be for monitoring the sensor device itsself (like battery of device or RSSI,...) but not for reporting the actual value for the sensor.

As a diabetic I rely on the blood glucose sensor which works well and updates fine so my wife can see the blood sugar. But the sensor does not show on default dashboard, because the sensor is a "diagnostic" sensor (`entity_type`). As it is still not possible in HASS to customize entities with customize.yaml and set `entity_category: None` (or similar), it is impossible to change this.

So see this as a feature request to finally add the possibility to change entities category using the hass customize integration.

The only workaround at moment is to generate a stupid template sensor that just uses `{{ states('sensor.pixel_8_uwe_blood_glucose') }}` which is adding extra work on HASS and also requires duplicating all health connect sensors like this.

So please either change the app to report the HealthConnect Sensors and default sensors and not "diagnostic" (this is clearly wrong, see above) or allow HASS to customize entities and change their category using customization.

Thanks, Uwe
