Add notes per exercise in the app

It would be helpful if customers could add a note for each exercise in the app. For example, to keep track of how an exercise felt, which weights they used, or any adjustments that were necessary.

How it works:
After completing an exercise, the customer can enter a short note.
Notes are saved and can be reviewed during future training sessions.
Coaches can view these notes and respond with feedback or adjustments to the schedule.
