Credit the import-contacts onboarding reward on account connection (#22354)

Onboarding V2 shows a credit reward for connecting an email account, but
the reward was only ever a frontend localStorage counter, never granted
server-side. This applies it for real.

When the connect-account step is actually completed via a Google or
Microsoft connection, the workspace is credited
`ONBOARDING_IMPORT_CONTACTS_CREDITS_REWARD`. Eligibility is derived
server-side from the `ONBOARDING_CONNECT_ACCOUNT_PENDING` flag (set once
at workspace creation), so the reward is one-time and is not granted
when the step is skipped. Crediting is best-effort: it never blocks the
OAuth flow and no-ops when billing is disabled.

The invite-team reward is handled separately in #22309. The upgrade
reward needs no grant: it is applied structurally through the trial
resource-usage cap, so an explicit grant would double-count it.
