Exercises (name + how-to note) are a new synced collection with the same
LWW/tombstone contract as events, served by POST /api/exercises/sync.
Training sessions are ordinary events (type "training") referencing an
exercise by id, so they ride the existing event sync unchanged.
The Training panel lists each exercise with last-trained / this-week /
streak stats, expandable instructions, and a one-tap Log button with the
usual undo/add-note snackbar. An exercise-by-day heatmap shows the last
14 days of consistency, and history and the daily overview count
training sessions like any other event.
