feat(chat): Campaign CH slice CH1 — retail LogTextType color table

Retail colors chat lines by the 34-value wire LogTextType (ACE's
ChatMessageType), NOT by acdream's synthetic 9-value ChatKind. The old
ChatWindowController.RetailChatColor(ChatKind) collapsed distinct retail
colors onto one bucket per ChatKind — e.g. every Channel line rendered
colorLightBlue (Magic's slot) when retail's actual palette spans five
different colors across the Turbine rooms and legacy allegiance family.

Ports ChatInterface::BuildChatColorLookupTable @0x004F31C0 verbatim
(RetailChatColorTable, all 34 RGBA floats read from the PDB-paired
binary's .data section) and threads a new ChatEntry.LogTextType field
through every ingestion site to the correct retail wire value:
HearSpeech/Tell pass the wire chatType through verbatim; Emote/SoulEmote
hard-code 0x0C; the Tell self-echo hard-codes 0x04; legacy ChatChannel
broadcasts derive their type from the channel bit via the new
LegacyChannelChatType helper (ported from the decompiled
Handle_Communication__ChannelBroadcast dispatch, hear vs. own-send);
TurbineChat rooms map through TurbineChatDisplayNames.LogTextType;
CombatChatTranslator's hit/miss/evade lines map to ACE's CombatSelf/
CombatEnemy per Player_Combat.cs; kill/death lines use retail's
decompiled 0x00 Default (not a combat color). ChatWindowController's
transcript now folds LogTextType through RetailChatColorTable with
retail's exact "out-of-range keeps the previous line's color" carry
rule; ChatPanel's combat highlighting sources the same table.

Corrects HearSpeech.cs's doc-comment ChatType legend (4 of 6 entries
were wrong). Adds register row AP-175 for the pre-existing (unchanged)
Popup-renders-in-chat divergence and updates AP-39's stale per-ChatKind
description. Narrows ISSUES #139 — its chat-colors half is done.

Retail renders no chat timestamp prefix path exists in acdream today,
so the "timestamp is always colorGrey 0x0C" rule has nothing to attach
to; noted here per the research doc rather than left silent.
