registryPages: correlate the trackDb settings docs with the cart, refs #37908 #37838

Two files in the tree say which track types a setting applies to, and they were
written from different evidence.  trackDbLibrary.shtml carries a hand-written
types list per setting, which is what #37908 has been correcting.
cartTrackVarCatalog files each cart variable under the config function that
reads it and records the trackDb types that function serves, which came from
reading hui.c and the per-type Ui functions.

Where a trackDb setting and a cart variable are the same knob, the two are
answering the same question, so they can be compared.  60 of the 261 documented
settings have a runtime override.  46 of those pairs are comparable, 12 agree
exactly, and 28 have a type the config code serves that the docs do not list.

The output is a candidate list, not a verdict, and the page says so.  Two known
false-positive shapes are called out on it: a variable read by two config
functions collects the types of both, and a pair joined by tdbDefault rather
than by name is weaker evidence, so those are reported separately.

Also factors the palette and the shared reset out of venn.css and index.css
into tokens.css, since a third page now needs them.
