fix(quest-tag): prefer live quest log tag over static QuestTag.lua data

Ascension sometimes reuses a Blizzard questId for custom content whose
group/tag status differs from the original (e.g. 253 "Bride of the
Embalmer" is a real group quest here but zeroed by QuestTag.lua for
TBC+/WotLK clients). Once a quest is accepted, QuestieDB.GetQuestTagInfo
now checks the live questLog entry's questTag before falling back to
questTagCorrections and the static QuestTag.lua table. Compat.lua gains
QuestTagNameToId, a reverse lookup built from questTagToName.
