feat(fleet): surface engine + agent session, editable config, timeline filter

Backend: insights now carry engine + sessionId/sessionUrl; releaseLease promotes
the reported engine onto the run (was created with the abstract engineClass,
usually 'unknown').

tracker-web job detail:
- Runs: show the concrete engine (insights.engine, falls back off 'unknown') and
  the agent session (Devin session id with a `devin --resume <id>` hint, or a
  link when a sessionUrl is present).
- PromptCard: edit repo/baseBranch/verify/autoMerge (not just the prompt) while
  draft/queued/blocked.
- Timeline: filter by event type (default collapses heartbeat runs).
- Show a "no PR — needs verify / not PR mode" hint when parked in review.
