`dueNudges` passed a JS Date as a parameter on the left of an interval
subtraction. postgres will not infer a type there and refused the whole
statement, so the tick threw once a minute and no nudge could ever fire.
the symptom was the worst kind: the row sat in the table enabled, sent_count
0, last_fired_at null — indistinguishable from a schedule that was armed and
simply had not come due yet. it was found by checking the row after arming it
rather than by trusting the log line that said "armed".
`now()` in sql instead, which also means the comparison uses the database's
clock rather than the platform's.
the test asserts only that the query EXECUTES. what broke was the sql being
invalid, and no amount of reasoning about interval arithmetic would have
caught that — only running it against a real postgres does.
