feat(api): wire opt-in per-client S3 API rate limiting (backlog#1191) RustFS shipped three rate-limiter implementations and none was wired to any request path: the tower layer never returned 429 (its over-limit branch passed requests through) and was never instantiated, the console env switches only logged, and the Swift token bucket was never called. Replace them with one working, default-off implementation: - Rewrite rustfs/src/server/rate_limit.rs as a sharded per-client-IP token-bucket limiter (32 mutex shards instead of one global RwLock write per request), bounded at 100k tracked IPs with lossless refilled-idle sweeps, returning 429 + Retry-After + x-ratelimit-* headers and an S3-style XML body. - Key on trusted-proxy-validated ClientInfo.real_ip, else the socket peer address; never read spoofable X-Forwarded-For/X-Real-IP headers. Requests without a resolvable identity fail open. The echoed request id is charset-gated to prevent reflected XML injection. - Wire the layer once at startup via option_layer between CatchPanicLayer and ReadinessGateLayer (external stack only), gated by new RUSTFS_API_RATE_LIMIT_ENABLE/_RPM/_BURST constants; health and profiling probes, internode RPC/gRPC, and the console are exempt. - Make RUSTFS_CONSOLE_RATE_LIMIT_ENABLE/_RPM actually enforce by reusing the same limiter core through an axum middleware. - Delete the dead Swift ratelimit module, its isolated tests, and the stale logging-guardrail entry; keep the live SwiftError 429 mapping. - Add unit tests (exhaustion/recovery with injected time, concurrency, cap eviction, spoofed-header and fail-open behavior, env matrix) and e2e tests proving 429 + Retry-After on the real server and zero behavior change with default configuration.
