anti 5ac8e0f91a feat(canary): honeydoc_docx + honeydoc_pdf generators ...

honeydoc previously emitted HTML only — operators picking 'Document'
out of the dropdown got a .html file dropped at /Documents/
quarterly_report.docx, which any attacker would clock the moment they
ran 'file' on it.

Two new generators that emit the real artifact format:

- honeydoc_docx: stdlib zipfile only. Builds a minimal but valid
  Office Open XML zip with the same Q3 review body as the HTML
  flavor and an external-image relationship pointing at the
  callback URL — same trick the operator-upload DOCX instrumenter
  uses, fetched on document open by Word and LibreOffice. Reuses
  _drawing() and _next_rid() from instrumenters/docx.py to keep
  the body/relationships shape identical between synthesised and
  instrumented files.

- honeydoc_pdf: pikepdf-backed. One-page PDF in the 14 base fonts
  (Helvetica, no font embedding), realistic body, /OpenAction /URI
  on the catalog so most viewers fire the callback on document
  open. Falls back to a clear error if pikepdf is missing so the
  operator can switch to honeydoc / honeydoc_docx.

Default placement paths now reflect each generator's true extension
(.html / .docx / .pdf) so the UI suggests something sensible. Both
generators surfaced in the New Token modal's generator dropdown.
