M10: print from the web build through the browser's print dialog (gap 4) (#1243)

Browse Source 
* Gates: fix two clippy failures on main

- ocr_ui: "Also recognize pages that already have text" used egui's own
  checkbox, which clippy.toml disallows (#1184 landed beside #1173);
  use widgets::checkbox like every other box.
- camera_edges: Rust 1.97's manual_range_contains; the rewrite keeps the
  old answer for a NaN angle (false) with an is_finite check.

* M10: print from the web build through the browser's print dialog (gap 4)

The web build had no printer: spool::submit refuses on wasm, so Print
could only download the print-ready PDF. Now its Print dialog offers
"Browser's print dialog" (the default there), which reaches every
printer the operating system knows.

- web_print: PdfCraft draws the print-ready PDF's sheets itself
  (engine Exporter), one sheet a frame since wasm has no threads:
  300 dpi up to 100 sheets, 200 up to 300, 150 up to 1,000, at most
  64 MP a sheet and 1 GiB of PNGs a job. The PNGs become blob URLs
  and print from a hidden srcdoc iframe, one sheet per page, margin 0.
- Chromium prints every page at the default @page size, so a sheet of
  the paper's size turned sideways is rotated 90 degrees CCW onto it
  (as drivers do); other sizes get named @page rules.
- Copies, two-sided and colour are greyed out (the browser's dialog
  sets them). If print() is refused (e.g. a sandboxed frame), the
  print-ready PDF downloads instead, with the reason.
- pdfcraft-print stays free of web APIs; six new strings in all 20
  catalogs (ATTRIBUTION hashes refreshed); docs and parity updated,
  gap 4 closed.

Verified in headless Chromium against a trunk build: three sheets at
300 dpi, the landscape sheet turned, no blank trailing page, and the
download fallback. Firefox and Safari not yet tried.
