Assist mode: taller live-note staff box (88px)

Browse Source 
The Assist card wrapped the LiveNoteStaff in .sheet-music-container,
which clips (overflow: hidden) — extreme ledger lines poked out of the
64px box by a few px. LiveNoteStaff now takes a height prop; stave y is
computed as (h-38)/2 - 40.5 (equals the old -28 for h=64). Assist uses
88px; mic bar keeps 64px.
