fix(proxy): stop stale auth cache re-publish so key updates and deletes propagate across replicas (#33565)
With enable_redis_auth_cache and multiple replicas, /key/update and
/key/delete delete the Redis auth blob and the handling pod's in-memory
entry, but two read-path writers re-published the stale blob from any other
replica's per-pod memory back to Redis with a fresh 60s TTL on every
request: the post-auth re-cache in user_api_key_auth and the spend writeback
in update_cache. Replicas whose in-memory entries expired then re-primed
themselves from the poisoned Redis entry, so key limit and access changes
never took effect fleet-wide while traffic continued, and a deleted key kept
authenticating.

The auth object is now written only by the DB-load paths
(IdentityStore._resolve_key, get_key_object): the post-auth re-cache is
removed outright (even a local-only write could race an invalidation and
resurrect a revoked key on this worker) and spend tracking no longer writes
the auth object back at all; spend is tracked through the spend🔑*
counters. The remaining spend writebacks for user, team, end-user, and tag
objects become local-only so they cannot republish stale management objects
either, with one deliberate exception: the proxy-wide
{litellm_proxy_admin_name}:spend scalar keeps its shared Redis write because
the global max_budget check reads it between authoritative DB reloads, and
it carries no limits or permissions so sharing it cannot resurrect an
invalidated auth blob.

DualCache's redis-to-memory read backfill also ignored default_in_memory_ttl,
pinning backfilled entries for InMemoryCache's 600s default instead of the
configured 60s auth TTL; the backfill now injects the configured default like
every write path already does, so a replica primed from Redis converges
within the auth cache TTL as well.

Consolidates the sibling stale-auth-recache branch; the delete-propagation
case is the duplicate ticket LIT-4350.
