teernisse 4740922b8d refactor(dashboard): simplify chat rendering and add scroll behavior ...

Removes unnecessary complexity from ChatMessages while adding proper
scroll management to SessionCard:

ChatMessages.js:
- Remove scroll position tracking refs and effects (wasAtBottomRef,
  prevMessagesLenRef, containerRef)
- Remove spinner display logic (moved to parent components)
- Simplify to pure message filtering and rendering
- Add display limit (last 20 messages) with offset tracking for keys

SessionCard.js:
- Add chatPaneRef for scroll container
- Add useEffect to scroll to bottom when conversation updates
- Provides natural "follow" behavior for new messages

The refactor moves scroll responsibility to the component that owns
the scroll container, reducing prop drilling and effect complexity.
