perf(rundown): keep entry revisions in step with the server

An entry revision advances on every change to that entry, which makes it a
cheap marker for what has moved on in a rundown. The client did not maintain
it: an optimistic entry carried the old revision, so the entry the server
returned always differed from ours by that one field.

That difference is enough to defeat structural sharing. A new entries object
recomputes the rundown metadata, which fires the effect behind the list, which
re-renders every visible row. Editing one title on a fourteen entry rundown
cost eight structural and sixty-one attribute mutations, twice over.

- optimistic patches apply the same revision bump the server does, so an
  unchanged entry keeps its identity and a refetch costs nothing to render
- the rundown metadata memo keys on the fields the derivation reads, so a
  change of rundown revision alone no longer churns the list
- editing an entry now reads the server response, which is the authority on
  what was applied, and only writes when it differs from what we predicted

Measured on the same edit: eight to four structural, sixty-one to forty-one
attribute mutations. Both changes are needed, neither helps on its own.

Two bugs found on the way. A swap stored the pre increment revision, so
swapped entries were indistinguishable from untouched ones. The optimistic
batch edit spread the request envelope onto the entry rather than the patch,
so it never applied the edit it was predicting.
