mod-paragon: ignore item AllowableClass for class 12 (gear + glyphs)

Paragon is a classless concept layered on top of WotLK class data: stock items and class glyphs gate equip / vendor visibility / loot rolls / AH 'usable' filter via ItemTemplate.AllowableClass, which never has the class-12 bit (0x800). Bypassing the gate at the five enforcement sites lets Paragon equip any class-restricted item -- including class glyphs, since EffectApplyGlyph itself has no class check beyond the item gate. Race / level / proficiency / skill / required-spell checks still apply, so Paragon can't skip baseline progression.
