Simplified Chinese: refine ambient light sensor terminology and tooltip wording

## Context

In the 11.1.1.1 release, with the UI language set to Simplified Chinese, the Time page shows `Ambient light sensor` and its unavailable-device tooltip in English when no sensor is detected.

I checked the current master branch before filing this: the three resource keys are already translated there, so I am **not reporting the missing release translations as an unresolved master bug**. Thank you for adding them. This is a suggestion to refine the terminology and phrasing, and include the translated strings in a future release.

## Suggested Simplified Chinese wording

File: `AutoDarkModeApp/Strings/zh-hans/Resources.resw`

| Key | Suggested value |
| --- | --- |
| `AmbientLightSensor` | 环境光传感器 |
| `AmbientLightSensor_ToolTip` | 根据环境光线亮度自动切换深色或浅色主题。 |
| `AmbientLightSensor_Unavailable_ToolTip` | 未检测到环境光传感器，因此此设备无法使用该功能。 |

Master currently uses “氛围光亮传感器” for the label and “氛围光传感器” in the unavailable tooltip. “环境光传感器” is a clearer, consistent description of an ambient-light sensor, while “氛围光” can suggest decorative/mood lighting. The suggested tooltip also states the detection result and its consequence directly.

I applied these strings locally in an unofficial personal preference patch: https://github.com/Tomclanc/AutoDarkMode-Personal-Patches . The patch is for my personal aesthetic/use preferences and explicitly recommends the original upstream app. This suggestion does not depend on adopting the other changes in that repository.

Update the three resource keys in AutoDarkModeApp/Strings/zh-hans/Resources.resw using the suggested Simplified Chinese values. Start by checking those keys and then verify the Time page with Simplified Chinese selected and no ambient light sensor detected; the wording and tooltip should appear in Chinese and consistently describe the sensor and unavailable feature.
