* Refactor: add pure pdf_ops module with real-PDF tests
* Drops tests we don't relly need + adds the typing annotation
* Now that I'm sure it works, re-work these tests to mock pdf_ops, rather than pikepdf
* Validates pages ahead of time in build_pdfs rather than during the building
* Adds the given/when/then and some additional cleanups of pytest style
* This is redundant now
Drops get_objects_for_user_owner_aware. Callers now use restrict_queryset_to_visible.
The same question was answered two ways, and the guardian path did not deny
deactivated users the way permitted_object_ids does.
* Chore: share one base class for the method-mapped permission classes
ViewDocumentsPermissions, TrashPermissions, PaperlessNotePermissions and
AcknowledgeTasksPermissions each repeated the same has_permission body and
disagreed on HTTP methods missing from their perms_map.
GlobalPermissionsByMethod now holds that logic once. HEAD is checked
against the GET entry and a method missing from the map is denied. The
task acknowledge map gains OPTIONS, now requiring change_paperlesstask
like POST instead of being open to any authenticated user. The global
statistics and system status checks also share their active and
authenticated preamble.
* Chore: type GlobalPermissionsByMethod.perms_map keys as HTTP methods
perms_map accepted any string key, so a misspelled method or a HEAD entry
would never match. Keys are now a Literal of the mappable methods, without
HEAD, and the map is typed read-only.
* 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
