fix: Address PR #695 review feedback for TooltipProvider refactor

- Add delayDuration={300} to global TooltipProvider in app.tsx to
  maintain consistent tooltip timing (previously many components used
  delayDuration={200}, so 300ms is a good compromise per review)
- Remove leftover TooltipProvider wrappers in task-node.tsx that were
  still referenced after import was removed (causing build failure)
- Remove leftover TooltipProvider wrapper in account-section.tsx
- Fix Tooltip+Popover nesting focus management issue in
  graph-filter-controls.tsx by adding onOpenAutoFocus={(e) =>
  e.preventDefault()} to PopoverContent components
