3e0adadf94 Dynamic Input: pointer input boxes with Tab, comma and relative entry (#60)
* Dynamic Input: pointer input boxes, Tab separator, relative entry

While a command asks for a point and Dynamic Input is on, the cursor
tooltip shows a pair of value boxes, following AutoCAD's pointer input:

- The first point of a command is X and Y, absolute.
- Second and next points default to polar (distance and angle) measured
  from the last point, so no `@` is needed.
- Typing `,` after a value locks it as X and moves to Y; `<` locks it as
  the distance and moves to the angle. A locked value holds the cursor and
  shows a lock.
- Tab types the separator for the format on show, so `40` Tab `90` is 40
  units at 90 degrees, and with the Cartesian setting `40` Tab `40` is 40
  over and 40 up.
- Enter or Space sends the entry with `@` in front, filling an empty box
  from the cursor. A plain number and Enter is still direct distance entry;
  `@`/`#` entries, keywords and command names go through untouched.

The command-line text is the single source of truth: the boxes are a view
of it, so the command line always shows exactly what will be sent
(`40,`, `40<90`) and Backspace simply edits it.

Tab is taken from egui in the raw input hook (desktop and web) while no
widget has focus. Otherwise egui moves keyboard focus to the next button on
Tab and the command line stops receiving keystrokes.

Two new settings mirror AutoCAD's: DYNPIFORMAT (1 = second points start
Cartesian) and DYNPICOORDS (1 = absolute), through SETVAR and in Drafting
Settings under Dynamic Input. The tooltip uses the theme tokens, matching
the command line.

Scripts, the control channel and MCP never pass through the boxes and keep
the plain command-line rules. The parsing lives in a small pure module
(dyninput.rs) with unit tests.
