Reinstate Direct Google Contacts One-Way Sync

While CardDAV works for syncing accounts in both ways, CardDAV is inherently client-dependent and introduces additional overhead (local account configuration, local client-side syncing etc.).

The discontinued one-way sync via direct Google Contacts integration offered cleaner cloud-based approach. It reduced reliance on local clients and provided a seamless way to treat Dex as the single source of truth for contacts.

Reinstating the direct Google Contacts one-way sync as an option alongside CardDAV would give users flexibility:

• Those preferring cloud-based sync could rely on Google Contacts integration as a one-way sync

• Those requiring two-way sync could continue to use CardDAV
