test(validation): unmount wrappers to fix pending fetch errors

Vitest was reporting 13 unhandled rejections with
'Closing rpc while fetch was pending' in Validation.spec.ts.

Root cause: Vue instances were never unmounted between tests,
so their beforeUnmount hooks never ran — isActiveView stayed
true and background microtasks (validate, refreshAfterAsyncSigning)
kept firing after the worker started winding down.

Fixes:
- Add outer afterEach(() => wrapper.unmount()) for the main wrapper
- Track local wrappers in the created() describe at scope level
  and unmount them in afterEach
- Unmount the inline localWrapper in the handleValidationSuccess
  describe immediately after use
