feat: handle mail bridge sync

[AlexisMora]

This PR adds Mail Bridge synchronization support on top of the changes from #1505

It updates Drive Desktop to use the Core revision that defines the resync, sync_started, sync_progress, and sync_finished control messages. Once the Bridge has completed its startup handshake, Desktop listens to its control channel and keeps the public, non-secret sync progress in the Mail Bridge service.

The main process exposes a narrow IPC surface for requesting a resync, retrieving the current sync progress, and subscribing to progress updates. The preload bridge forwards those APIs to the renderer, and the Settings Mail Bridge view subscribes to them so it can render live synchronization state and invoke the existing resync action
