Prasanna721 b439e7ea01 fix: chat messages saving broken (#730)
1. New chat messages saving to old thread (race condition)
2. Feedback modal null handling issue (boolean | null not coerced to boolean)
3. Wrong icon on Integrations tab (was Cable, now Sun)
4. Wrong icon on Graph tab (was LayoutGridIcon, now GraphIcon)
  5. Missing cursor pointer on header tabs
  6. Default view was "graph" instead of "list"
