* fix(proxy): count global proxy spend for every request with a user, cached on this worker or not

* fix(proxy): add global proxy spend with an atomic Redis increment that never re-creates a reset counter

The global proxy spend bump read the total, awaited, and wrote old + cost back
from a background task, so a budget reset that deleted the key in between got
the pre-reset total written back, and workers overwrote each other's totals.

RedisCache.async_increment_if_present runs INCRBYFLOAT only when the key
exists, keeping its TTL, and this worker's copy is then set from the shared
total with no await between its read and write. The bump now runs whenever a
proxy max_budget is set, matching the DB writer, and the armed post-call read
and the batch-read declaration it used are removed.

* fix(proxy): report the global spend Redis increment to service metrics and request traces

The global proxy spend increment now emits Redis service success and
failure events under the spend_counters target and passes the request
span through, so it shows as redis.incr spend_counters like the write
it replaced.

The unit tests run the real RedisCache increment against fakeredis
instead of mocks, and a new test checks the span lands under the
request span on success and on a Redis failure.

* test(proxy): keep the spend counter Redis fake off the network

* test(proxy): count increment_if_present as a shared-cache call in the key-family guard

* fix(proxy): keep the newer global spend total when Redis replies arrive out of order
