fix(billing): refresh workspace billing status after completed top-up (FE-932) (#12787)

## Summary

A completed workspace top-up refreshed only the balance, leaving billing
status — and `subscription.hasFunds` (derived from
`statusData.has_funds`) — stale until the next status fetch. The
completed handler now refreshes both.

## Changes

- **What**: `TopUpCreditsDialogContentWorkspace.vue` completed branch —
`await fetchBalance()` → `await Promise.all([fetchBalance(),
fetchStatus()])` (both already exposed on `useBillingContext()`).
- **Breaking**: none.

## Review Focus

- Pre-existing bug (predates the B2 facade; `main`'s top-up already
called `fetchBalance` only). Test validity proven by reverting to
balance-only → the completed case goes red on the `fetchStatus`
assertion.
- Tests: completed → both refresh; pending / failed → neither (3 cases).

Fixes FE-932
