Answers which tier the caller is on, what it allows, and what is left to spend.

`effectiveAvailable` is the ONLY figure to compare against zero. The others are
its parts — prepaid money, granted credits and the daily term are three sources
of one spend, not three balances to add up a second time.

A tier that cannot be READ is an error, never Free. The router in front of the
models maps any non-2xx to Free, so answering Free from a question nobody could
answer would pin every paying customer to the most restrictive row with nothing
anywhere to find.

A named handler, not a closure, so zipdoc can lift this prose into the registry.
