Fix #696: the Properties panel's number fields are all one width

The Transform fields were sized from the row's room, the rotation field was
70 pt, the corner radius 80, Opacity 64, the stroke weight 90 and Keyboard
Increment 80, so the fields didn't line up. One `panels::field_width`, the
Transform fields' width measured from the full row, now sizes all of them (and
the Edit Artboards fields, and the Transform panel's corner radius).

 This file tracks **how far we are and what's left**. Time estimates are wall-clock hours of continuous Claude Opus 5.5 agent work (including builds and the CI gate), given both for **one agent** and for **4–6 parallel agents** on disjoint crates. They are counted from the remaining work (see [Parity estimate](#parity-estimate)), calibrated against measured throughput, and updated as work lands.
