name the live opencode rows

They were permanently unnamed, and the two halves needed to name them already existed on
officer: the sidecar reports its own sessionKey because that is all it has, while the ses_ id
arrives separately over opencode:session and is recorded in opencode/state.ts. Nothing joined
them. /chat/live joins them now, so no protocol or sidecar change — widening
LiveOpenCodeSession would have meant sending the sidecar a fact it told officer in the first
place.

One list call names every row rather than one transcript load each, and it is skipped when
nothing is running or no id has been reported, so an idle Live panel never touches the serve.

Verified against a real turn, which also showed the design working as intended: the first
poll has no id yet and shows nothing, the next shows title and cwd. That window is real and
short, and showing nothing beats showing a key the user has never seen.

Worth knowing: opencode titles its own sessions "New session - <ISO timestamp>", so the row
is located but not meaningfully named. That is genuinely its title, not a bug here.
