Rust connect admission and password ordering

RE-919. Reproduce with python3 scripts/analyze_rust_connect_admission.py; focused validation: cargo xtask test-group rust-connect-admission. Machine report.

Rust matches160 original173979 admission prefixes, preserving bot bypass, address-before-password rejection, none/empty server password behavior, exact case-sensitive password results, messages and userinfo selector order. Typed invalid domains preserve selector state. Native userinfo/filter population and complete caller acceptance remain open.

Original executable/native runtime and complete Linux/macOS Rust/Bevy/Solari acceptance remain unverified.
