Fix Launchpad mode MIDI receive and color palette

Browse Source 
- Fixed note matching bug: removed channel check so notes 36-45 match
  across channels 1-3 (Launchpad static/flashing/pulsing)
- Simplified LED lookup to match by note only (channel stored for mode)
- Replaced sparse palette with proper RGB gradients between key
  breakpoints (Red, Orange, Yellow, Green, Cyan, Blue, Purple, Off)
