fix(ci): apply rustfmt to cluster auth throttle helper

[cursor]

Fixes CI failure on #186 where cargo fmt --check rejected formatting of all_cluster_auth_buckets_throttled in src/cluster/security.rs.

Applies cargo fmt to match the project's rustfmt rules.

Note

Low Risk
Formatting-only Rust change with no logic or security behavior differences; lockfile is a minor dependency patch bump.

Overview
Fixes cargo fmt --check CI by reformatting all_cluster_auth_buckets_throttled in src/cluster/security.rs: the signature and the .values().all(...) closure are laid out per project rustfmt rules. Behavior is unchanged—still returns whether every tracked IP bucket is at the cluster auth failure limit.

Cargo.lock also bumps transitive tinyvec from 1.13.1 to 1.13.2 (checksum only; no source edits tied to it).
