fix(android): resolve SharedPreferences mismatch and document cross-platform storage pattern

- Fix TestNativeFetcher to read from same SharedPreferences as plugin
  - Changed PREFS_NAME from 'DailyNotificationPrefs' to 'daily_notification_timesafari'
  - Changed KEY_STARRED_PLAN_IDS from 'starred_plan_ids' to 'starredPlanIds'
  - Updated getStarredPlanIds() to read from plugin's SharedPreferences location
  - Added diagnostic logging for plan ID loading

- Add updateStarredPlans() call in App.vue mounted() hook
  - Ensures starred plan IDs are persisted to native storage on app startup
  - Allows native fetcher to read plan IDs from SharedPreferences
  - Added diagnostic logging for configuration flow

- Document cross-platform storage pattern
  - Created docs/CROSS_PLATFORM_STORAGE_PATTERN.md with architecture flow
  - Documented TypeScript → Capacitor bridge → Plugin → Native storage → Native fetcher flow
  - Added iOS implementation checklist with code examples
  - Clarified why native storage is needed (background workers can't use bridge)

- Add JWT generation logging to test-user-zero.ts
  - Log JWT algorithm (ES256K) and DID when token is generated
  - Helps diagnose JWT verification issues

Fixes:
- Empty planIds array in native fetcher requests
- SharedPreferences key mismatch between plugin and native fetcher
- Missing documentation for iOS implementation

All changes maintain backward compatibility.
