fix: resolve cross-platform contactMethods JSON parsing inconsistencies

- Add platform-agnostic parseJsonField utility for contactMethods handling
- Update contact export functions (contactsToExportJson, contactToCsvLine)
- Fix contact storage in QR scan views (ContactQRScanShowView, ContactQRScanFullView)
- Ensure consistent JSON string storage across web SQLite and Capacitor SQLite
- Prevents "[object Object] is not valid JSON" errors when switching platforms
- Maintains compatibility between auto-parsing web SQLite and raw string Capacitor SQLite

Fixes: contactMethods parsing errors in export and QR scan functionality
