fix: Add @kbx alias to vite.config, update screens.ts imports

- Add @kbx alias to vite config for @kbx/contracts resolution
- Update screens.ts to use KBX v60 ScreenDefinition contract
- Register 3 new pages: ShadowRunQueue (T06), ModelList (T02), ApprovalQueue (T03)

Fixes import resolution for KBX components in page registry.
