* Mark the thumbnail constants Final
* Comment each pdftoppm option
* Feature/Chore: Replaces all usages of ImageMagik's convert binary with a simple Pillow based helper
This removes ImageMagik as a dependency entirly and all documentation is cleaned up from it.
We no longer need to install it, have a policy for it to allow PDFs and no longer shell
out to it either.
* Fix: Save WebP images losslessly when removing the alpha channel
Pillow's default WebP save is lossy, so a WebP with an alpha channel came
back from remove_alpha_channel with slightly shifted pixel values before
it reached OCR. Save WebP lossless; other formats are unchanged.

* Chore: Generate PDF thumbnails with pdftoppm and Pillow instead of ImageMagick
Replace the ImageMagick convert based PDF thumbnail path with pdftoppm and
Pillow. Keeps thumbnails at 500px wide for small and odd sized pages, covers
the qpdf repair and double failure paths, removes the unused run_convert
helper, hardens thumbnail encoding, deprecates PAPERLESS_CONVERT_MEMORY_LIMIT
and PAPERLESS_CONVERT_TMPDIR, and corrects the related docs and CI.

* Chore: Supersample the PDF thumbnail render 2x
Render the PDF page at twice the target size and downsample, with edge case
handling for small and odd sized pages, simplified helpers and tests, and
trimmed comments.

* Fix: use a fractional thumbnail DPI so oversized pages render a bounded raster
* Deprecate the unused PAPERLESS_GS_BINARY setting too
* Warn at startup when pdftoppm is missing
* Resample PDF thumbnails once instead of twice with LANCZOS, still never enlarging
* Read PDF page size from pdfinfo so it matches pdftoppm
* Mark the thumbnail constants Final
* Comment each pdftoppm option
scikit-learn treats a single-class fit as binary, so predict_proba returns
[1 - p, p] for one class and argmax could index past classes_. Use only
column 0, the real class, so the confidence threshold still applies.
get_public_filename relied on sanitize_filename to truncate, which cuts
from the end and so dropped the counter and extension of long titles.
Multi-byte titles could also exceed the 255 byte filesystem limit.
Shorten the title by UTF-8 bytes before appending the counter and
extension. The exporter reserves room for its longer derived thumbnail
and archive suffixes.
get_users_with_perms includes group members by default, so PDF actions such
as merge and split gave them direct grants on the new documents, which
outlived their group membership.
The trash list needs to show a version to whoever owns its root document, but
it deliberately shows only owned and unowned documents and ignores explicit
shares, so it cannot use permitted_object_ids. #14384 gave it its own
filter_queryset with a hand-built condition through the root, which describes
the same rule as the annotations in permitted_object_ids a second time.
Move those annotations into annotate_authorizing_fields. PermittedObjectsFilter
gains a parent_field attribute that its owner-only and granted paths both use,
and the trash filter shrinks to setting include_granted and parent_field.
