fix(codes): encoding progress follows the work

The QR percentage counted phases and the display froze at 90 % once
encoding ended, so the first opening sat at 90 % while the slow stages
ran. Each 2D symbology now weights its phases by measured cost,
interpolates inside the long ones, and the display splits encode,
pack and runs; a cached code counts its runs from 0.
