The RC2 encrypt and decrypt operations used the expanded key schedule without checking that a key had ever been configured. On a zeroed or otherwise unkeyed context the ECB ops ran over an all-zero schedule and returned success, and the CBC wrappers inherited the same behavior, so a caller who skipped wc_Rc2SetKey received ciphertext under an unintended key with no error signalled. Guard wc_Rc2EcbEncrypt and wc_Rc2EcbDecrypt on a zero keylen and return MISSING_KEY when no key has been set. The CBC wrappers call these and propagate the error. Mirrors the existing 3DES keySet guard. Add a regression test covering the unkeyed path for all four ops.
