Support for iMessage / SMS Sync on PC (Windows)

Request to enable syncing of iMessage and SMS messages on PC (Windows) so that users who use Dex on a computer, not just on iPhone or Mac, can still sync their last messages and have them logged in their CRM/contact timeline.

This would allow users on Windows platforms to benefit from full message-sync functionality, ensuring their SMS/iMessage interactions are captured irrespective of the device they use.
