pm-mobile: top dropdowns, ±10 tempo, Play/Practice split, collapsible log

Browse source 
Reworks the mobile player's controls per use on a phone:

- Set list + track are now two dropdowns at the top (with the volume slider +
  theme/fullscreen beside them); drops the hamburger/bottom-sheet menu. The
  track dropdown stays in sync with prev/next and set-list auto-advance.
- Tempo grid adds coarse -10/+10 buttons above the fine -/+ buttons, laid out
  as a 4-col grid with prev/next and play/practice in the centre columns.
- Separate Play and Practice transports: Play runs the metronome without
  touching the practice log; Practice runs AND records a session
  (metronome.logs, same format/key as the editor: {at,name,durationSec,bpm,
  lanes}, per-track history, sub-3s blips skipped).
- Tap Tempo restyled as a real button.
- Collapsible practice log: a thin bar at the bottom opens a bottom-sheet
  showing past sessions for the current track (date - duration @ bpm), with
  per-entry delete and clear-this-track.

Landscape phones switch to a two-column layout (pulse left, transport right) so
everything fits without vertical overflow. Engine untouched.
