RateLimiter::check_and_increment now takes &TenantContext, and
rate_limit_key emits buzz:{community}:ratelimit:{pubkey_hex}:{suffix}.
Same pubkey active in two communities consumes two independent quotas,
matching the S1 cross-community isolation fence in the buzz-relay
rewrite spec.

check_ip_connection stays operator-global by design. The IP fence runs
at connection acceptance, before host->community resolution has
completed (or, on resolve failure, instead of it). Threading
&TenantContext through it would invert the order of operations. Per-
(community, IP) caps, if ever needed as a tenant-fairness signal,
belong in an additive LimitType keyed on (community, ip) — not in this
trait.

RedisRateLimiter in buzz-pubsub follows the new trait signature.
AlwaysAllowRateLimiter test impl mirrors it. Two new tests pin the
behavior: the key includes the community prefix, and same-pubkey-two-
communities yields two distinct Redis keys.

Local cargo test -p buzz-auth: 36 passed. Local cargo test -p
buzz-pubsub: 3 passed, 6 Redis-required ignored. Workspace-wide check
not run locally (sqlx 0.9.0 requires rustc 1.94, local toolchain is
1.89 — same constraint Max hit on the pubsub lane); relying on CI for
the full integration compile.
