Root cause of minimap pin drift on Sunstrider Isle: on Ascension,
GetCurrentMapAreaID() returns 3430 for Eversong, but mapIdToUiMapId only
had the WotLK mapping (463→1941). This meant actualUiMapId was nil in
GetCurrentPlayerPosition(), causing the parent→child zone conversion to
be skipped entirely. Eversong-zone coords passed through tagged as
uiMapID 1241, producing wrong world positions and pin drift.
Fix: add Ascension areaId→uiMapId mappings (3430→1941, 3431→1241) to
mapIdToUiMapId after UiMapData init. Now the conversion path triggers
correctly: Eversong coords → world coords (via 1941 bounds) →
Sunstrider zone coords (via 1241 bounds).
One-line fix in Compat.lua. No changes to HBD.lua or projection logic.
