A pfUI-native group-loot roll history window built on ClassicAPI's
C_LootHistory backport, adapted from the anniversary Blizzard reference.
- Movable/scrollable window (ESC-closable, Clear button) listing rolled
items; each row expands to per-player rolls.
- Item icon/name/quality rendered via the !!!ClassicAPI Item mixin
(Item:CreateFromItemLink + ContinueOnItemLoad), so uncached items load
asynchronously and repaint their row.
- Winner shown on the collapsed row (name/roll/roll-type) and marked in the
expanded list with a checkmark left of the name (matches the reference).
- Expansion state keys on the stable rollID; events (FULL_UPDATE /
ROLL_CHANGED / ROLL_COMPLETE) drive a rebuild while shown, and re-attach
the scroll child so a growing list scrolls without a /reload.
- Toggle via /loothistory or /lh; optional auto-show on new rolls behind
loothistory.autoshow (default off).
