2a35a1a76f M11: Optimize PDF and Reduce File Size run in the background with a progress bar (#370)
* M11: Optimize PDF and Reduce File Size run in the background with a progress bar

Advanced optimization and Reduce File Size did all their work on the UI
thread, so on a large file the window stopped repainting until they were
done and looked as if it had crashed.

- pdfcraft-optimize: optimize_with_progress reports each image and the
  clean-up; returning false stops with OptimizeError::Cancelled.
- engine: Session::optimize_job captures a copy of the document and the
  choices; OptimizeJob::run reports each OptimizeStage (removing user data,
  images, cleaning up, merging, writing), stops on request with
  EditError::Cancelled and turns a panic into an error so a worker always
  reports back. optimized_bytes is the job run in place.
- ui: both commands run the job on a worker thread (inline in tests and on
  the web), like OCR and Export. A card at the bottom centre shows the
  stage ("Optimizing... image 14 of 40"), a bar that eases towards the
  fraction with a light sweeping across it, the percentage and Cancel;
  notices stack above it. A second run is refused while one is going. The
  control channel's state includes the progress.

The headless doc_optimize and doc_reduce tools stay synchronous. New
strings are translated for es, fr, ja, zh-hans, zh-hant.

* Clippy: as_chunks in the signature image background test (follow-up to #355)

#360 switched the image test to as_chunks; #355 added another chunks_exact(4)
in the background test, which clippy's chunks_exact_to_as_chunks rejects.
