The Camellia encrypt and decrypt operations used the key schedule without checking that a key had ever been configured. A zeroed or otherwise unkeyed context has a keySz that does not match 128, 192, or 256, so the underlying block transform hit the default no-op case and CBC emitted an easily reversible XOR chain while still returning success. A caller who forgot wc_CamelliaSetKey received a success code with effectively unencrypted output. Add a key-state check that accepts only valid Camellia key sizes and have wc_CamelliaEncryptDirect, wc_CamelliaDecryptDirect, wc_CamelliaCbcEncrypt, and wc_CamelliaCbcDecrypt return MISSING_KEY when no key has been set. Mirrors the existing 3DES keySet guard. Add a regression test covering the unkeyed and garbage key-size paths.
