Subject: [PATCH] fix(webapp): show save button while first exercise is in
 progress

Save button was gated on workout.length, which stays 0 until a
second exercise is started (the transition that flushes the current
exercise into workout[]). Single-exercise workouts had no reachable
save path.

Gate on workout.length OR currentExercise sets, and recompute
visibility when sets are added/removed and on draft restore.
