- When clicking a session card, switch to the correct project and viewMode
  ('chat' for home sessions, 'experts' for expert sessions) instead of only
  setting the active session ID
- Persist session scope via sticky ref so switching to non-conversation tabs
  (knowledge, tasks, etc.) no longer jumps to the first expert's sessions

- Keep useMemo pure by extracting ref writes into useEffect
- Remove redundant ternary in openSession
