LOAD_TEMPLATE_MODTABLES now returns a templateID -> modTable map that
ForgeManager owns (vendorModTables). ForgeManager.forgeItem, WorkOrder
validation and the ManageNPCMsg forge item list read it through
ForgeManager.getVendorModTable(), and ItemTemplate.modTable is removed.
Values are unchanged: static_vendor_items has 5089 rows, one per
templateID, all present in static_item_templates, modTable 0-30.
Templates not in the table still read 0. The old loader stopped at the
first templateID missing from ItemTemplate.templates; there are none.
No comparator added or removed.
