fix(map): robustly hide Callboard/Contract Board quests below 60 (#10)

Ascension board bounties (e.g. NPC 24 'Outlaw's Contract Board') aren't
reliably flagged repeatable, so IsRepeatable missed them and their ! kept
showing below 60. Add QuestieDB.IsBoardQuest (detects starter NPC/object
names containing 'board', cached per quest); the hide-below-60 option now
hides repeatable OR board quests in both the draw path and ShouldBeHidden.
