fix(revenuecat): guard NaN in time-ms mappers and require integer days

- Block params mapper: only clear duration/extendByDays when the parsed
  endTimeMs/expiryTimeMs is finite, so invalid input does not silently
  discard the user's valid companion default
- defer_google_subscription: validate extendByDays as integer (was
  Number.isFinite), matching the error message
