Pull request overview

This PR fixes QUIC/TLS connection reuse by ensuring wolfSSL_clear() fully resets QUIC encryption-level tracking state via wolfSSL_quic_clear(), preventing stale read/write level state from incorrectly affecting subsequent connections on the same WOLFSSL*.

Changes:

• Reset the remaining QUIC encryption-level fields (enc_level_{read,read_next,write_next}) in wolfSSL_quic_clear(), bringing QUIC state back to the same baseline as a fresh QUIC WOLFSSL*.
• Add a regression test that performs a full QUIC handshake, calls wolfSSL_clear(), and verifies the client’s QUIC read/write levels return to wolfssl_encryption_initial and that Initial-level data is accepted again.

File	Description
src/quic.c	Resets all QUIC encryption-level fields during wolfSSL_quic_clear() so reuse via wolfSSL_clear() starts from Initial state.
tests/quic.c	Adds test_quic_clear_reuse to validate QUIC state reset behavior after wolfSSL_clear().
