topology/log-sse: resolve team container name for coding-loop runs

The log SSE endpoint was always resolving the container name from a
research topic id (research-<topic_id>-team). For paired coding loops
that own a team_id, the actual container the topology worker spawns is
team-<team_id>-container (spawn_team) — not the research topic's one.
That mismatch produced a stream of 404s from Docker:

  Docker responded with status code 404: No such container:
  research-<topic_id>-team

Mirror topology_worker::try_team_gateway_url's precedence:
  1. run's loop has team_id → team-<team_id>-container
  2. run has research_topic_id → research-<topic_id>-team
  3. loop.source_research_topic_id (legacy paired flow) → same as 2
  4. else → clear error, no more 404 spam
