[Bug] macOS Bing Wallpaper fails to load in zh-CN locale due to HTTP/HTTPS conflict

Environment:

OS: macOS (Apple Silicon)

App Version: Bing Wallpaper 2.0.14

System Language: Simplified Chinese (zh-CN)

Symptom: The app homepage displays "Failed to load", and attempting to set the wallpaper prompts "Failed to set wallpaper".

Root Cause Analysis: By running the app binary in the terminal with RUST_LOG=trace, the following error is caught in the startup log: ERROR bingwallpaperapp_lib::scheduler: Initial rotation check failed: Only HTTPS URLs are allowed

The app strictly enforces HTTPS for images (the CSP also only allows https://*.bing.net). However, the backend API ([https://services.bingapis.com/ge-apps/api/v2/bwc/hpimages](https://services.bingapis.com/ge-apps/api/v2/bwc/hpimages)) returns http URLs when queried from the Chinese market (mkt=zh-CN), for example: [http://ts2.tc.mm.bing.net/th?id=](http://ts2.tc.mm.bing.net/th?id=)... For mkt=en-US, it correctly returns [https://www.bing.com/th?id=](https://www.bing.com/th?id=).... Because the zh-CN API returns HTTP, the app's own security policy blocks it. This also explains why users reported that temporarily switching the system language to English "fixes" the issue.

Temporary Workaround (No system language change required): Force the app to run in English via terminal: defaults write com.microsoft.bing.wallpaper AppleLanguages -array en-US Relaunching the app resolves the issue.

Suggested Fix:

Update the backend API to return https URLs for the zh-CN market.
