fix: tune orbs/aurora/pulse/rain, redesign rays with settings

Browse Source 
Orbs: opacity halved — ambient, not a flood of color.
Aurora: opacity halved, 6 bands, slower movement.
Pulse: fast bass tracker (0.45 factor) for onset detection; ambient
  rings so mode stays alive without audio playing.
Rain: 30 drops (was 65), 1.4px wide, soft gradient, bass mult 2.5x.
Rays: complete redesign — tapered triangle beams from center using
  linear gradients; secondary counter-rotating pink layer; center glow.
  Reads raysConfig (count/speed/brightness/spread) via ref — no restart.
Settings: rays config panel (4 sliders + reset) appears when rays active.
bgStore: RaysConfig interface, setRaysConfig, localStorage persistence.
