iPhone numeric practice pacing is ready

A numeric practice should show the plan for the day, not only one total. The next TestFlight build can now receive the same privacy-safe pacing facts used by the mobile web practice row.

• Each scheduled set keeps its exact time and completion state.
• Manually logged progress covers the earliest remaining sets without inventing check-ins.
• Partial progress stays visible as an exact remainder instead of being rounded away.

The current iPhone build keeps its existing response, while the next build explicitly opts into the richer display.
