Every time in UTC, and every day as YYYY-MM-DD (closes #313)

AbuseIPDB's daily count keeps its day as a civil.Date, taken from the UTC
clock and written to reputation.json as "YYYY-MM-DD"; it was a time.Time
at midnight. Every time read from a state file is converted to UTC, so a
time an admin writes with an offset is written back in UTC.
TestMainRunsDiscriminator runs sww discriminator with TZ 14 hours ahead
of UTC and checks that the process line, the request line and
clients.json are in UTC. SPEC.md states the rule near its start;
AGENTS.md makes it an iron rule.
