Look up a preset by id from the FULL definition set (including a layout not currently
OFFERED because its nominal count exceeds EQ_MAX_BANDS, e.g. geq31) —
undefined for an unknown id. Deliberately broader than EQ_PRESETS: a picker
must never show a preset that doesn't fit, but the underlying data + honest
EqPreset.capNote stay resolvable for callers that already have the id (a
persisted session, a future larger-cascade build).
