_process_pdf prepends "\n\n[PDF content]:" to extracted text, and two
call sites in document_routes.py stripped it with .lstrip("\n[PDF content]:").
str.lstrip(chars) treats its argument as a *set of characters*, so it keeps
eating into the page text that follows the marker — e.g. a body starting
with "to the board" loses its leading "to" because 't'/'o' are in the
marker's character set. Replace both sites with a shared
strip_pdf_content_marker() helper that uses str.removeprefix.

"""Regression test: the '[PDF content]:' wrapper must be removed without eating

The old call sites used ``str.lstrip("\\n[PDF content]:")``, which treats the

argument as a *set of characters* and keeps stripping leading characters that

happen to be in that set — corrupting the start of the extracted document.
