feat(D.2b): exact retail chat colors from a live cdb dump

Attached cdb to a live retail acclient (PDB-matched) and read the named RGBAColor
constants at acclient 0x81c4a8+ (colorWhite/colorBrightPurple/colorLightBlue/
colorGreen/colorLightRed/colorGrey), used by ChatInterface::BuildChatColorLookupTable
@0x4f31c0. Replaced the approximated RetailChatColor palette with the ground-truth
values: speech=white, tell=colorBrightPurple(1,.498,1), channel=colorLightBlue
(.247,.749,1), system/popup=colorGreen(.5,1,.498), combat=colorLightRed, emote=colorGrey.
Capture scripts saved under tools/cdb/.
