fix(server): bypass workspace cache in onboardingStatus resolver (#20322)

## Summary

In multi-instance deployments, `coreEntityCacheService` memoizes the
workspace entity per server for ~10s, bypassing Redis hash invalidation.
After `activateWorkspace`, if the next `currentUser` query is routed to
a stale replica, the server returns `onboardingStatus:
WORKSPACE_ACTIVATION` and `workspaceMember: null`, the client redirects
to `/create/profile`, and submitting the form throws "User is not logged
in". Reproduces on prod/staging only (local dev = single instance).

Fix: in `OnboardingService.getOnboardingStatus({ user, workspaceId })`,
read the workspace directly from `WorkspaceEntity` repository (bypassing
the per-instance core entity cache) so `onboardingStatus` reflects the
freshest `activationStatus` right after `activateWorkspace`, even when
the request hits a replica with a stale cached workspace.

## Test plan

- Prod/staging: sign up + create workspace, verify `/create/profile`
works and form submits.
- Local: regression on the full onboarding flow.
