AVIdeo has Video Password Protection Bypass via API Endpoints Returning Full Playback Sources Without Password Verification

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `get_api_video_file` and `get_api_video` API endpoints in AVideo return full video playback sources (direct MP4 URLs, HLS manifests) for password-protected videos without verifying the video password. While the normal web playback flow enforces password checks via the `CustomizeUser::getModeYouTube()` hook, this enforcement is completely absent from the API code path. An unauthenticated attacker can retrieve direct playback URLs for any password-protected video by calling the API directly. Commit be344206f2f461c034ad2f1c5d8212dd8a52b8c7 fixes the issue.
