Add pause, remap, speed/volume, reorder genres, full README

UI improvements:
- Start button now sticky at bottom of viewport — always visible
  without scrolling, with Remap Pads button alongside
- Pause/Resume: press Escape or pause button in HUD. Suspends
  AudioContext to freeze all scheduled audio perfectly.
- Back to Menu button on pause overlay

Gamepad remap:
- Remap Pads button walks through each pad (Red, Yellow, Blue,
  Green, Kick) and captures the button press from any USB drum kit
- Mapping saved to localStorage, survives page reload
- Default mapping still Wii Rock Band

Speed & Volume sliders:
- Speed: 50%-150%, affects BPM for drum patterns and note/bg
  timing for classical pieces. Slow down for practice.
- Volume: 0%-150% master volume, affects both drums and synth
- Both on menu Settings card

Genre tab reorder:
- Synth genres now appear first: Singalong, Christmas, Folk,
  Classical, Video Games, Chiptune Originals
- Drum pattern genres after: Rock, Metal, Jazz, etc.
- Default genre changed from Rock to Singalong

README: Complete song list for all 65 synth pieces + 120 drum
patterns, USB drum kit compatibility table, feature list.
