Add English localization (device-language based)

Add English as an overlay localization following the device language,
keeping Simplified Chinese as the base/development language. Untranslated
strings fall back to Chinese automatically.

- project.yml: set developmentLanguage zh-Hans and knownRegions (zh-Hans/en/Base)
- Resources/en.lproj/{Localizable,InfoPlist}.strings: ~230 English strings
- Resources/zh-Hans.lproj/InfoPlist.strings: Chinese permission prompts
- Restructure ternary Text/Label and String-typed UI messages so they
  localize (String(localized:), LocalizedStringKey helper params); replace
  a .contains("通过") success check with a dedicated flag
- Localize user-facing model/coordinator/error messages across App and Shared

Internal RuntimeLogger logs and diagnostic/report bodies remain in Chinese.
