fix(ui): scroll chat to bottom on initial load

Browse Source 
The chat view was starting at the top showing oldest messages instead of
scrolling to the bottom to show the latest messages (like WhatsApp).

Root causes:
1. scheduleChatScroll() was called without force flag in refreshActiveTab()
2. The scroll was targeting .chat-thread element which has overflow:visible
   and doesn't actually scroll - the window scrolls instead

Fixes:
- Pass force flag (!chatHasAutoScrolled) when loading chat tab
- Wait for Lit updateComplete before scrolling to ensure DOM is ready
- Scroll the window instead of the .chat-thread container
- Use behavior: 'instant' for immediate scroll without animation
