Tests ahead of the change: with maintenance_mode on, both image routes
must answer 503 with a Retry-After header and the JSON error body, while
the health check keeps answering 200 and reporting maintenance_mode, and
the login page and /metrics keep answering 200; these fail until the next
commit. With it off, image requests must still reach the image handlers.
The test server now also builds the health check, which these tests
request.

POST / had no limit, so the signing key could be guessed at no cost. It
is now limited to 5 attempts per minute per client by a new RateLimit
middleware on github.com/go-chi/httprate; an attempt over the limit gets
429 with Retry-After. It counts by the address the ClientIP middleware
resolved through trusted_proxies (an IPv4-mapped address as its IPv4
address, IPv6 by its /64) and runs after the body-size and CSRF checks,
so every attempt that reaches the key comparison is counted. README says
that with the default trusted_proxies a client with a private address
can choose its counted address, and how to close that.
