refactor: move static data to db

[ljosberinn]

• preload data during build through createStaticData
  already preloadable:

  • dungeons
  • affixes (also only deliver affix ids via fight response)
  • soulbinds
  • covenants
  • classes (add spec icon to schema / db)

• Ability already covers name id and icon

• only cds need to be separately stored in AbilityCooldowns or something, linking to spec
