Sketch dimensions: make Tab commit, instead of silently dropping what you typed

The inline editor special-cased Escape and Skip()ped every other key, so Tab fell
through to wx's default navigation. Its popup frame holds exactly one control, so
focus came straight back to that control with its text re-selected.

Type 60, Tab, 40, Enter — expecting to fill two dimensions — and the 60 is gone: Tab
neither committed it nor advanced, so the 40 just replaced the re-selected text. A
re-selected field is pixel-identical to a freshly opened one, so nothing on screen says
a number was dropped. Tab-to-next-dimension is what Onshape, SolidWorks and Fusion do,
which is exactly why it is the key a user reaches for.

Tab now calls do_commit(), the same path Enter takes; the caller's on_commit is already
what walks to the next dimension. Verified by driving the GUI: 37 Tab 24 Enter now
produces a 37.0 x 24.0 rectangle, where before it produced 24 and a mouse-derived value.
