fix: docker compose build reference to old chdb-rust ref

[austin-barrington]

Description

Docker compose is cloning and using a hyperbytedb chdb rust lib, our changes were merged into main upstream so we can remove the branch dependencies.

PR Summary

Low Risk
Build and lockfile-only changes; risk is mainly that main chdb-rust could diverge from what was tested on the feature branch until CI passes.

Overview
Switches the default chdb-rust git ref from feat_arrow_insert to main everywhere builds clone that path dependency: root Dockerfile, hyperbytedb-proxy/Dockerfile, scripts/checkout-chdb-rust.sh, and .github/scripts/checkout-chdb-rust.sh. CI, local checkout scripts, and docker compose image builds now pull upstream main after the Arrow insert work landed there.

Cargo.lock is refreshed with widespread transitive crate version bumps (HTTP stack, TLS, tokio, serde, etc.)—no application source changes in this diff.
