Updates go through the collection cell: collid- and version_id-exact

The last unverified flow failed on its guess — the collection row has no
link named "own"; the edit affordances are icon anchors with no text. The
site offers something far better, now verified: the row's VERSION CELL
carries its own collid in an onclick, and the inline editor it opens is a
radio list whose values ARE version ids.

So an update addresses the copy by collid and the edition by version id —
no name matching, no pagination, no dialog, and structurally incapable of
creating a duplicate entry (it sets one field on one collid). Clicking
the radio fires CE_SaveData itself; there is no Save button, and the save
has landed when the cell stops reading "Editing". A version id the editor
doesn't offer aborts with the entry untouched.

The class docstring's UNVERIFIED list is now empty but for the
second-copy add, which --verify already reports as a copy-count
shortfall.
