fix(cli): record API key history when creating project via CLI (#431)

Dashboard has onboarding flow so it doesn't need to record the initial
API key, but CLI creates and sets the default project directly. This
adds a best-effort RecordKeyRotation call (same as key rotation) so the
initial key appears in project_secret_key_rotations history.
