Add colored SCA-style flavor wheel to cupping; colorize the radar chart

- New flavor-wheel.js: two-ring sunburst (families inner, descriptors
  outer) in SCA hue families; tapping a wedge toggles the same flavor
  tag as the checkbox list; selections render bold with a dark outline;
  respects the tag limit; labels drawn above all wedges so long names
  never clip (screenshot-verified in headless Chromium)
- Cupping radar: one hue per attribute on labels + vertex dots
