fix(dashboard): flair tints and Basic lighting as the client computes them

Browse Source 
- Flair tints are the terrain file's color bytes over 255, times the flair
  model's own vertex colors (FlairAssets::AppendRenderBuffer divides by
  255.0). The manifests said 63, so in the game shaders' sRGB maths tints
  of up to 4 turned the flairs white (Battle Against Frakjaw's leaves).
  Conversion format 6, so flair manifests kept by browsers are fetched
  again.
- BasicShaders, AlphaAsAlpha and Flair.fx multiply the light by the vertex
  color and only then clamp, as the COLOR0 output; the views clamped the
  light first, so a light brighter than 1 no longer lifted darker vertex
  colors.
- Docs: the flair tint, the clamp, and that AlphaAsAlpha cards show their
  backs (Cullmode none) from outside a playable area.
