ProCapNet label and facet color fixes from QA. refs #35528

The composite longLabel named the sequence-contribution scores, which only
exist on hg38, so it was wrong on hs1. Use "ProCapNet predicted PRO-cap" on both
assemblies; the scores are described on the track description page.

The Sample class swatches reused two colors from the cell-line palette, so a
track's color could be read as its class: A673 is a cancer line and drew in
#0072B2, which was the Non-cancer swatch. Sample class is a binary facet and
does not need a hue, so use black and gray, outside the Okabe-Ito palette.

Say in the description that the contribution scores cover about 1% of the
genome, so the limit is visible before the display conventions section.

 This track holds two kinds of output from those models:
 </p>
 
 <ul>
 <li><b>Predicted PRO-cap</b>: what the model expects the PRO-cap signal to be,
 at every base of the genome, on both strands. The sequence rules that govern
 where initiation happens are largely shared between cell types, so any one model
 highlights sequence capable of driving initiation, including at regions where no
 PRO-cap experiment has been done.</li>
 <li><b>Sequence contribution scores</b>: how much each individual base pushed
 the model's prediction up or down. Bases inside a functional element such as a
 TATA box or an initiator carry high scores, and the pattern of high-scoring
 bases often spells out the recognition sequence of a promoter-associated
 transcription factor. These are computed only around MANE Select transcription
-start sites.</li>
+start sites, so they cover about 1% of the genome and the track is empty
+everywhere else.</li>
 </ul>
 
 <p>
 The predictions are available on GRCh38/hg38 and T2T-CHM13/hs1. The contribution
 scores are available on GRCh38/hg38 only, because they are computed at MANE
 Select transcription start sites and MANE is not defined for T2T-CHM13.
 </p>
 
 <p>
 Predictions are not measurements: they say what the sequence looks capable of,
 not what a given cell is doing. The matching experimental data is in the PRO-cap
 track, available on GRCh38/hg38.
