Danny a529416599 feat(tg-fitness-bot): structured mini-app, edit workouts, draft persistence
Rebuilt Log view: exercise name input with autocomplete, per-set
entry (reps x weight), exercise cards with edit/remove. Comma and
dot both work as decimal separators. Notes field. Collapsible raw
text input as fallback.

Edit saved workouts from History (pencil icon). Loads exercises
into editor, Save becomes Update, Cancel returns to History.

localStorage draft persistence: auto-saves on every state change,
restores on reopen (24h expiry), clears on save.
