fix(protocol-dashboard): remove '1.0.0' validator-version fallback so fetch actually runs (#14356)

## Summary
Follow-up to #14355. The dashboard was still showing `1.0.0` for the
Validator current version after that PR shipped. Root cause: the
`getCurrentVersion` selector returned `'1.0.0'` as a fallback when
`services.validator.currentVersion` was undefined, and
`useCurrentVersion` only dispatches `fetchCurrentVersion` when the
selected value is `undefined`. The hardcoded fallback short-circuited
the dispatch, so the new `getNumberOfVersions` + `getVersion` logic
introduced in #14355 never ran.

- Remove the `?? '1.0.0'` fallback from the selector so the fetch
dispatches.
- Harden the `setCurrentVersion` reducer to initialize
`state.services.validator` if it doesn't exist yet, since
`fetchCurrentVersion` can resolve before `fetchServiceStakeValues`
populates it.

## Test plan
- [ ] Open the dashboard and confirm `Register a Node` → `Current
Version` shows the latest onchain version (currently `1.1.0`) instead of
`1.0.0`.
- [ ] Hard refresh and confirm no race-condition crashes from
`setCurrentVersion` running before service info loads.
