[Icons] Add an Informational semantic color family

Face-down play and the exile zone are states that are neither a gain nor a
loss, and the pre-#7595 art painted them blue (arrow_right_blue). #7595 dropped
that hue, and the icon engine has had only Positive and Negative since, so both
states fall back to neutral ink.

Add the family with the same three-level ladder the other semantic roles use:
authored roles per theme, scheme defaults otherwise, an emphasis mapping, the
palette-editor rows and the generator seed. The defaults clear the 4.5:1 label
floor on both schemes and the ladder's saturation ordering; the existing
emphasis, hue and preview tests now cover the new family. Preview sheets that
name roles resolve an unauthored one through the same default the client
paints.
