Editions become changeable — losslessly

Eric hit a diff version-disagreement and found there was no way to
revisit a set edition: the Titles pick-edition button only appeared
while the version was UNSET. It now shows as "change edition" on
version_auto/version_approved rows — and reopening the ballot no
longer clears the current pick, because change must be lossless:
abandoning the ballot keeps the approved edition, the lingering id is
inert while ambiguous (is_confident_version gates diff and upload),
and the next decision overwrites or clears it.

Help documents the other half of the disagreement story: the pipeline
NEVER edits a version already set on a BGG collection entry (the
additive-only rule), so a diff disagreement is resolved either by
changing the pipeline's pick here or by fixing the entry by hand on
BGG.
