feat: Make background effect clearer and more visible

- Increased dotSize from 2 to 6 (matches auth page)
- Disabled showGradient to remove internal darkening
- Lightened radial gradient: 100% opacity → 50%, 100% radius → 60%
- Lightened top gradient: solid black → 80% opacity

The dot matrix effect is now much more visible like on /auth page
