Pull request overview

This PR aims to fix video streaming when mTLS (client certificate auth) is enabled, particularly for notification video playback and MJPEG streaming, by ensuring the right URLSession/Alamofire delegates are used and that AVFoundation uses custom URL loading when needed.

Changes:

• Add an mTLS-capable Alamofire SessionDelegate for MJPEG streaming that also emits the response-boundary notification.
• Update HomeAssistantAPI.VideoStreamer() to select the correct delegate when a client certificate is configured.
• Enable AVFoundation custom URL loading for HLS streams when a client certificate is present (in addition to security exceptions).
