security: harden handshake/masking flows and add adversarial regressions

- forward valid-TLS/invalid-MTProto clients to mask backend in both client paths\n- harden TLS validation against timing and clock edge cases\n- move replay tracking behind successful authentication to avoid cache pollution\n- tighten secret decoding and key-material handling paths\n- add dedicated security test modules for tls/client/handshake/masking\n- include production-path regression for ClientHandler fallback behavior
