* Issue #1028: OCR can read pictures on pages that already have text

Recognize Text skipped every page with text, so a picture of text on a
page that also has real text never became searchable. The engine and
the ocr_recognize tool already had skip_text_pages, but the desktop
dialog never offered it, and turning it off read the page's own text
again and added it a second time, so search found every word twice.

- Engine: always collect the page's own glyph boxes; with
  skip_text_pages false, a recognised word at least half covered by
  them (an earlier OCR layer included) is left out. OcrPage counts
  those words as already_on_page. The default still skips pages with
  text.
- Dialog: "Also recognize pages that already have text", kept with the
  other choices and used by Recognize text in multiple files too.
- Tools: ocr_recognize reports already_on_page; ocr_recognize_files
  accepts skip_text_pages.
- The two new labels in the 15 catalogs that translate the OCR dialog.
- Synthetic tests (a picture of a sentence plus real text) for the
  engine, the tool and the dialog; the engine test fails with the
  filter turned off. Unit tests for the coverage check, including
  NaN, infinite, inverted and overlapping boxes.
- parity, docs/roadmap.md M10 row and the ROADMAP.md progress log.

* Issue #1028: Czech labels for the OCR text-pages option

The Czech catalog was completed (#1066) while #1028 was in review, and
czech_covers_ui_literals requires every tl! literal: the two new
Recognize Text labels were missing, so the test failed after the merge.
