Refine mockup: set lists, per-beat patterns, theming, shortcuts

- Tempo ramp gains a start BPM and signed (up/down) steps.
- Presets and set-list items now capture practice settings (trainer + ramp).
- Set-list items: per-item ▶/⏹ play, 💾 save-back, per-item history view.
- Log & backup moved into a ⋯ menu; "+ Add meter" moved below the lanes.
- Light/dark theming (OS-aware + toggle, persisted) and mobile/desktop responsive layout.
- Keyboard shortcuts (Space/T/↑↓/A/R/N/1-9/?) + help overlay; fixed dead Tap button.
