v1.3.0-dev03

Third dev pre-release toward v1.3.0. High-priority fix, grab this over dev02 if you use the Android app.

Fixed

• Editing a set (weight, reps, or the completed checkbox) could revert a moment later, sometimes on every edit, especially under a slow or unstable connection. Root cause was a too-frequent background refresh serving a stale on-device cache over an edit that had already saved. See the CHANGELOG for the full technical breakdown.

If you hit the reverting-edits issue on dev02 or earlier, this is the fix, please try it and let me know how it holds up.
