Bug 1 (critical): setTheme lacked try/catch around wx.setStorageSync.
If storage write throws (full / permission), the theme silently
fails to persist but UI has already changed → on next cold start
getCurrentTheme falls back to orange.
→ Wrap in try/catch; still apply UI change even if storage fails
(better to see the right color now than revert immediately).
Bug 2 (display): settings onShow called applyThemeToPage (updates
'theme' object) but never refreshed 'currentThemeId'. After tab
switching, the radio highlight showed the wrong theme.
→ Add setData({ currentThemeId }) in onShow.
Redundancy: theme now also saved as themeId in user_settings.
getCurrentTheme falls back to user_settings.themeId if app_theme
key is unexpectedly missing, providing a recovery path.
