perf(onboarding): compute invite suggestions on-demand (#21696)

## Summary

Follow-up to #21640. In production, invite suggestions took ~1 minute to
appear because `FetchOnboardingInviteSuggestionsJob` ran on the shared
`calendarQueue` behind heavy calendar-sync jobs.

- **Drop the background job entirely.** `getInviteSuggestions` now
resolves the connected account from the authenticated
`@AuthUserWorkspaceId()` and computes suggestions on demand:
cache-first, with a bounded calendar fetch + cache write on a miss.
Removes the Google/Microsoft enqueues, the
`shouldComputeInviteSuggestions` threading through the auth controllers,
and the now-unused `shouldComputeInviteSuggestionsOnConnect` /
`isOnboardingConnectAccountPending` helpers.
- **Prefetch one step earlier.** New `usePrefetchInviteSuggestions` hook
fires the query from `CreateProfile` so the server cache is warm by the
time the invite step renders. `InviteTeam` switches from `network-only`
→ `cache-first`. If the profile step is skipped, the invite step still
computes on-demand (~1–3s, no queue) — no more minute-long waits.

No GraphQL schema change.

## Test plan

- [ ] Connect Google calendar in onboarding → invite step renders
prefilled teammates with no perceivable wait
- [ ] Connect Microsoft calendar in onboarding → same
- [ ] Onboard with workspace name already set so profile step is skipped
→ invite step still prefills (just with a brief on-demand fetch instead
of 1 min)
- [ ] Connect a non-work-email account → invite step renders empty form
(no suggestions)
- [ ] `npx nx typecheck twenty-server` ✅
- [ ] `npx nx lint:diff-with-main twenty-server` ✅
- [ ] `npx nx lint:diff-with-main twenty-front` ✅ (changed files clean)
- [ ] `google-apis.service.spec.ts` + `microsoft-apis.service.spec.ts`
pass
