When a quest object node is opened/looted, that specific node's
map/minimap pin now disappears immediately even before the objective is
fully collected, instead of all node pins staying until turn-in.
On LOOT_OPENED, QuestieQuest:RemoveLootedObjectivePins finds the active
object-objective spawn nearest the player's world position (<=12 yd),
marks it consumed in Questie.db.char.lootedObjectSpawns, and repopulates
just that objective so clustering recomputes with the node skipped.
_DetermineIconsToDraw skips consumed object spawns, so removal persists
across redraws and /reload. ClearLootedSpawns runs on AcceptQuest, so
abandoning and re-doing the quest (including after an Ascension prestige)
shows every node again.
Works in every data source mode (auto/learner/static/none): suppression
is centralized in the shared _DetermineIconsToDraw that all redraw routes
funnel through, operating on the mode-resolved objective.spawnList.
Matching is radius-based (1.5 zone units) so a learner spawn re-added at
the player's position for the just-looted node is suppressed too.
Scoped to object-type objectives; monster/kill pins are unchanged.
