Subject: [PATCH] pm-kit: draw the real metronome screen on the panel (static
 sample data)

Switch the firmware from the bring-up diagnostic to pm_ui::draw_metronome with
static borrowed lane data (no allocator yet). Shows the actual metronome UI on the
device; live track + moving playhead come when pm-core is linked.
