Fix: consolidate born-digital PDF detection between archive decision and OCR (#13409)

* Fix: unify born-digital PDF detection between archive decision and OCR

should_produce_archive() and RasterisedDocumentParser.parse() each
reimplemented the "does this PDF have real text" check independently,
using different normalization of pdftotext output. Raw pdftotext output
can be non-empty (whitespace/form-feed layout padding) even when there
is no real content, so the two checks could disagree: consumer.py
treated a tagged-but-textless PDF as born-digital and skipped the
archive, while the parser's own (stricter, normalized) check found no
text and ran OCR anyway, leaving the document with no archive despite
real OCR text (GH #13387).

Both call sites now share one predicate, pdf_born_digital_text() in
paperless/parsers/utils.py, so they can no longer drift apart.

* Fix: restore extract_text seam for born-digital detection in parse()

parse() had switched to calling pdf_born_digital_text() directly for
its initial text/born-digital check, bypassing the parser's own
extract_text instance method. That broke test mockability (tests patch
tesseract_parser.extract_text to control the born-digital decision)
and caused CI failures with mismatched OCR call counts and text.

Split pdf_born_digital_text() into is_born_digital_text(text, path,
log) - a pure decision function - and a thin pdf_born_digital_text()
wrapper for callers without text in hand (consumer.should_produce_archive).
parse() now extracts via self.extract_text(None, document_path) and
passes the result to is_born_digital_text(), restoring the seam with
no change to production behavior.

* Cleanup: simplify born-digital detection, close #13387 test gap

Simplification pass over the born-digital detection consolidation:
- is_born_digital_text(): drop the has_text temp for an early return.
- consumer.py: standardize the archive-decision log lines on plain
  hyphens (was a mix of em-dash and hyphen) and hoist the duplicated
  text_length computation.
- Parametrize TestPdfBornDigitalText instead of four near-identical
  tests.

Code review follow-up: the existing tests only ever exercised
pdf_born_digital_text() through mocks, so the actual #13387 scenario
(a tagged PDF whose only "text" is layout padding) was never checked
against real pdftotext/pikepdf output - a regression in the
normalize-before-decide logic itself would have gone undetected.
Moved tagged_no_text_pdf_file from parsers/conftest.py up to the
shared paperless/tests/conftest.py (it was previously only visible to
tests under parsers/) and added a non-mocked regression test against
the real sample file.

Also fixed two stale comments in test_consumer.py referencing a
_extract_text_for_archive_check helper that no longer exists.

 ### Bug Fixes

@@ -620,6 +620,34 @@ no other workflow will be executed on the document.
 If a "Move to Trash" action is executed in a consume pipeline, the consumption
 will be aborted and the file will be deleted.
 
+##### Password Removal {#workflow-action-password-removal}
+
+"Password Removal" actions attempt to remove password protection from encrypted PDF documents. You can specify:
+
+- One or more passwords to try, separated by commas or new lines
+- Each password is tried in order until one successfully unlocks the document
+
+Password removal never modifies a file in place. Instead, once a working password is found, the
+decrypted content is consumed as a new [document version](#document-file-versions), leaving the
+original (still encrypted) version in the document's version history.
+
+**Consumption Started**: because this trigger fires before the document exists yet, the password
+removal itself is deferred until after the initial consumption of the encrypted file has completed.
+OCR engines cannot process an encrypted PDF, so this first version is typically stored with no
+extracted text (unless the file already contained extractable text outside of OCR). Immediately
+afterwards, the password is removed and the decrypted file is automatically re-consumed as a second,
+new version of the same document, this time with normal OCR/text extraction applied. In other words,
+a password-protected file added with this trigger will briefly exist as an un-OCR'd version before
+the properly processed version is created.
+
+**Document Added**, **Document Updated**, **Scheduled**: these triggers run against a document that
+already exists, so password removal happens immediately: the decrypted content is queued for
+consumption as a new version right away. Note that if the document's initial consumption also
+happened while it was still encrypted, that original version will likewise be missing OCR text.
+
+**Current limitation**: Passwords are stored as a simple list without descriptions. To handle
+multiple PDF types with different passwords, create separate workflows for each use case.
