Summary: Add a button to manually trigger an immediate Git repo sync for Transformations, instead of only relying on the automatic background sync.

Problem: After I push new code to my Git branch, Transformations Git Sync doesn't pick it up right away. I currently have to refresh the browser repeatedly until I see that the last sync completed less than a minute ago. In practice this costs me 2–5 minutes of waiting and guesswork on every single change.

Impact: This friction adds up quickly during active development, where fast iteration matters. The repeated manual refreshing is inefficient and there's no way to know when a sync will actually happen.

Proposed solution: A "Force Sync" (or "Sync now") button in the Transformations UI that immediately pulls the latest commit from the connected Git repo, with a visible status/timestamp confirming when the sync completes.

Benefit: Eliminates the wait-and-refresh cycle, gives developers control over sync timing, and speeds up the develop-test loop.
