Frogman: API tokens stored in plaintext

Frogman provides headless PBX control through MCP and HTTP API. Prior to 1.6.2, Frogman stored API tokens generated by Tools/CreateApiToken.php:33-36 as raw bin2hex(random_bytes(32)) strings in oc_api_tokens, and Frogman.class.php:78 authenticated the X-Frogman-Token header by comparing it with the stored raw value, allowing database read access to recover reusable active tokens at their assigned permission level, including admin. This issue is fixed in version 1.6.2.
