fix(styles): resolve style captions through in-app language

Style card descriptions were passed to Text as raw String keys, so they
never went through AppL10n. Resolve them (and the editor title) with the
in-app UI language override, matching the rest of the host app.

+### Fixed
+- **Style card captions**: resolve each built-in style’s short description through the in-app language override, so switching App Language updates the caption instead of showing a localization key or the system language. / **风格卡片说明**：内置风格的说明小字改为走应用内语言设置；切换 App 语言后说明会跟着变，而不再显示本地化 key 或跟随系统语言。
