resolve live sessions by claude's id, not the agent's session key

Every live row read 'Starting…' and linked nowhere, because the title lookup searched for a transcript
named after the session KEY. It isn't. The key is officer's handle for a conversation; the transcript is
named after Claude's own session id, and the mapping between them exists only inside the agent
(setClaudeSession/getClaudeSession). I assumed the two were the same and never checked — confirmed wrong
by looking for the ids from the officer log under ~/.claude/projects and finding nothing.

claude:list now reports claudeSessionId beside the key, the route resolves titles by that, and rows link
to it. Null means the first turn has not reported one yet, which is a genuinely unwritten conversation
and stays unlinked.

Needs the agent sidecar restarted to take effect — the new field comes from there.
