Remove barChartMerge from the mouseDevTimecourse tracks, it washes out the bar colors. refs #37001

barChartMerge fades a merged group's color toward white when the group has fewer
than 100 members. scaleColorPart() in facetedTable.c blends with maxVal 240 by
(threshold - count)/threshold, with threshold 100. That is built for the
Cell Browser single-cell tracks, where the facet count is a cell count in the
hundreds or thousands.

This track is bulk RNA-seq and its .facets count is 1 per sample, so merging by
tissue and time point gives a group count of 2. The blend is then 0.02*color +
0.98*240, which lands every channel at roughly 235-240: thymus #C8B400 rendered
as #EFEFEB. Measured on a rendered image at chr12:56694976-56714605, the track
went from 40 saturated colors to 0.

Reverting the setting restores the colors on both assemblies, verified against
the .facets palette. Also reverts the description page wording back to one bar
per replicate, and drops "grouped and" from the shared Display include since
grouping was only available through this setting.

The rest of the QA changes are unaffected: maxWindowToDraw, barChartMetric,
labelFields and defaultLabelFields are still in place, whole-chromosome renders
are still 245 ms, and the details page reports 156 of 156 bars again.
