Swaps the plain line sparkline for an ordered-dither AREA chart matching the
dither-kit house style, and moves it from the embed thumbnail to a full-width
image below the fields.

- renderDitherChart (@tripwire/utils): ports the dither-kit's exact Bayer 4x4
  ordered-dither into the server PNG renderer. Each column fills from its value
  line to the floor with the Bayer scatter (dense at the floor, dissolving up to
  a soft value-line border), varying only alpha. Painted into a low-res backing
  buffer then nearest-neighbor upscaled, so the cells stay chunky and pixelated —
  same pipeline as the web charts. Actual paints behind, billed rides on top
  thinned so the layer behind reads through.
- embed.image (was embed.thumbnail): the chart renders large under the grid.
