Fix n_chase pattern to properly chase through all LED positions

Browse Source 
- Replace oscillating behavior with proper chasing movement
- Use pattern_step for internal tracking instead of controller's step
- Calculate position relative to chase head: (i - pattern_step) % num_leds
- Chase head moves through all LED positions with n3 step multiplier
- n1 controls width of lit chase segment
