feat(themes): chat channel color sets for four built-in themes

Hellion Arctic, Event Horizon, Moonlit Bloom and Mint Grove each
ship a distinct chat-channel palette tinted toward their brand
family while preserving the FFXIV channel identity (Say light, Yell
yellow, Shout orange, Tell pink-magenta, Party blue, FC cyan, NN
green). Chat 2 Klassik intentionally ships without — users picking
that theme keep their existing channel colours.
