One named syncInterval replaces the two 24-hour literals in the scheduler: a
successful run now waits 12 hours, and an account becomes due again 12 hours
after its last successful sync. Two background fetches a day stay inside Enable
Banking's documented allowance of roughly four per account per day, which a
failing sync's hourly retries also draw from, so the bank rate limits that
prompted this are no more likely than before.
