PanosandClaude Opus 5 8e09bd8463 fix(plot): follow the fixture's page-setup conventions ...

A drawing saved by a commercial CAD application (tests/fixtures/plot,
provided by Panos: one 10 m line, three layouts) corrects several
assumptions of the previous commit:

- rotation is relative to the medium's own orientation: an unchanged sheet
  keeps the driver's exact medium (its PDF driver lists landscape media of
  its own, written with rotation 0; a system printer's portrait A3 plotted
  landscape carries 90); only a newly picked sheet is written as the
  catalogue's portrait medium
- the stored scale factor (DXF 147) is the ratio × 25.4 on millimetre page
  setups and the plain ratio on inch ones; the "use standard scale" bit
  stays clear for standard and custom scales and is set for fit-to-paper;
  a standard code is kept across a paper-unit conversion ("1:1" on an
  inch page setup over a millimetre paper space is 1 in = 25.4 units)
- layout plots take the same scale path as every other area, so a foreign
  layout's paper-space unit survives
- "plot with plot styles" / "display plot styles" round-trip as the
  dialog's checkboxes, independent of a style table being named
- layout limits place the sheet at minus its displayed margins, the way the
  source application does (the printable corner is the paper-space origin);
  the margin ↔ rotation mapping shared by the printable-area guide now
  turns the medium's top margin into the layout's left one at 90°

The fixture round-trips through the dialog with every stored field
unchanged; picking a new sheet on it writes the canonical form.
