Function: getPrintableArea()

function getPrintableArea(engine: PrintEngine, media?: MediaDescriptor): PrintableArea;

Resolve the chassis dead-zone for a print, with the standard precedence: per-roll media tag (when present) > engine-level field > zeros.

The media argument is optional so the helper is usable from encoders that haven't resolved a media yet (e.g. status probes). When media carries printableHorizontalOffsetMm / printableVerticalOffsetMm, those values override the matching edges on the engine field; the unaffected edges (right, trailing) keep their engine-level values.

Always returns a fully-populated object — callers never need to ?? 0 individual edges.
