mod-paragon: let class 12 actually USE class-restricted glyphs / items

Browse Source 
Two paths still rejected glyph use on Paragon characters even after the
earlier AllowableClass server bypass:

1. Spell::CheckItems (server) treated cast-from-glyph as a normal
   "equipped item required" cast and called HasItemFitToSpellRequirements,
   which only handles weapon/armor and falls through default for
   ITEM_CLASS_GLYPH -> SPELL_FAILED_EQUIPPED_ITEM_CLASS. Skip that check
   when the cast item itself is the glyph.

2. The 3.3.5 client engine pre-checks ItemTemplate.AllowableClass against
   the player's class locally and refuses the right-click before sending
   CMSG_USE_ITEM, regardless of what the server would do. Bake the
   Paragon class bit (1<<11 = 2048) into AllowableClass for every
   class-restricted item via a mod-paragon SQL migration so the engine's
   pre-check passes for class 12.

Cache caveat: clients that previously inspected an affected item have
the old AllowableClass cached in Cache/<locale>/itemcache.wdb; deleting
the Cache folder forces a re-query. The server also caches item_template
in memory at boot, so this migration only takes effect for clients after
a worldserver restart (or .reload item_template) once the SQL has been
applied -- DBUpdater handles the SQL automatically on the next start.
