Make toast notifications more informative

- Server: Add bodySnippet, identifier, issueTitle to comment_added
  activity details so the UI can show comment content
- Client: Show comment snippet in comment toasts instead of just
  "posted a comment on PAP-39"
- Client: Add agent title/role as body text in agent status toasts
- Client: Show trigger detail in run status toasts for context

PAP-31
