For developers: what the fix changed

The fix implements the moHeadlessApiKeyIsValid and moHeadlessRejectApiKey methods in miniorange_2faController.php to perform a constant time API key comparison without returning the key in the response. It also introduces a dedicated backdoor token generated by hooks in miniorange_2fa.install to further separate secrets.

Also in this release The release also updates module version metadata and restricts the headless routes to accept only post requests.
