style: fix canvas controls visibility and enhance dot grid background

Browse Source 
- Add !important to all React Flow dark theme overrides to ensure they
  win over library default styles (fixes white controls rectangle)
- Add SVG fill inheritance for control button icons
- Use slightly lighter canvas background (bg-accent/30) so dot grid
  is more visible
- Increase dot size and use muted-foreground color for better contrast
