alehelandClaude Opus 5.5 ba33257fa3 fix(sign,cos): signing leaves out what was added and removed again
The signing saves wrote with default options, so a redaction mark added
and cleared in the session (or a comment added and deleted) reached the
file through a signature, a timestamped signature, embedded LTV evidence
or a document timestamp, with its QuadPoints, overlay text and authors.
A signed revision can't be changed afterwards, so nothing could take it
out again.

`sign`, `sign_with_timestamp` and `dss::embed` now save with
`drop_unlinked`: everything they add is reachable (the signature through
the field's `/V`, the store from the catalog), and the ByteRange
placeholder is found in the written bytes.

`timestamp_document` can't: its `/DocTimeStamp` dictionary has no field
pointing to it, so the option would drop it and every document timestamp
would fail with "ByteRange placeholder not found". It frees the leftovers
first with the new `Document::free_unlinked_additions`, which frees
exactly what the option leaves out, and then adds the dictionary.
