chore(deps): cargo update

Refresh Cargo.lock to the latest semver-compatible versions of all
dependencies (no Cargo.toml constraint changes). Notable bumps include
tokio 1.52.1 -> 1.52.3, postgres-types 0.2.13 -> 0.2.14, rust_decimal
1.41.0 -> 1.42.1, reqwest 0.13.3 -> 0.13.4, and tower-http 0.6.8 -> 0.6.11.

cargo build, clippy --all-targets -D warnings, fmt --check, and the full
test suite (against Trino 479) all pass.
