feat: improve background with low-poly triangular pattern

- Replaced square grid with triangular mesh for more organic look
- Increased default cell size from 75px to 150px for subtlety
- Added variance to point positions for natural randomness
- Each cell now renders two triangles with gradient fills
- Maintains theme colors and daily variation
