alehelandClaude Opus 5.5 a9b0db12c6 fix(edit): show backgrounds on pages that paint their own white backdrop ...

Add Background draws behind the page content, so on a page that first
fills itself with opaque white (browsers' Save as PDF, print drivers) the
background was hidden completely and the tool looked broken.

- pdfcraft-edit: new `backdrop` module. A strictly detected backdrop (one
  axis-aligned `re`, opaque white in a device colour space, painted before
  anything else and covering the crop box) is replaced by turning that one
  fill into `n` in a per-page copy of its stream; the original stream is
  left untouched for other pages. Remove background restores it, unless
  the copy was edited since. Page-sized pictures (scans) are reported only.
- Background gains `replace_backdrop` (default on); the default colour is
  a visible light yellow instead of near-white.
- Dialog: offers to replace the backdrop, warns about scanned pages,
  checks pages a few per frame, preview draws text over the colour.
- Automation: `doc_background` takes `replace_backdrop`; new read-only
  `doc_backdrops` lists pages with a backdrop.

Acrobat's behaviour on such pages is unobserved; recorded as our choice
in parity/.
