fix(rundown): narrow rundown invalidation

Two independent issues in the revision strategy.

The client guard only skipped a refetch when the revision matched exactly,
while its comment described skipping anything not newer. A message which
arrives after a refetch has already brought in a later revision forced a
needless refetch. Compare with <= so the guard does what it claims.

Renaming a rundown re-initialised it, which stops playback. Renaming the
loaded rundown during a show therefore stopped the show. A title has no
bearing on the schedule, so it now goes through an ordinary transaction:
the title is persisted, the revision bumped and clients notified, with no
runtime involvement. Renaming to the current title is a no-op.
