fix(map): completed/accepted/repeatable available-quest pins (#7 #9 #10)

#7: Completed quests kept showing as available '!'. The server completed-
quest list arrives async via QUEST_QUERY_COMPLETE, often after available
quests were first drawn. Recalculate available quests once char.complete is
populated by that event so completed quests are removed (also clears the
already-completed subset of #8).

#9: An accepted quest's available '!' could linger on the minimap until
/reload. UnloadQuestFramesByDataType unloaded the frame but left its name in
questIdFrames and _G; it now removes those references so the icon is torn
down immediately on both map and minimap.

#10: Added 'Hide repeatable quests below level 60' (Icons tab, off by
default) to hide repeatable available quests (e.g. the Ascension Callboard)
from map/minimap until level 60. Enforced in _DrawQuestIfAvailable and
ShouldBeHidden so existing minimap pins are removed too; reappear at 60.

Lint: selene 0 errors. Tests: 145 successes / same 7 pre-existing failures.
