Added configuration steps for pipeline locking methods (source timecode and video alignment) in channel settings, including input requirements.

Security assessment

Changes provide operational guidance for synchronization methods without mentioning security vulnerabilities, incidents, or protective features. Focus is on functionality, not security.

+     * **SOURCE_TIMECODE** (default): Uses embedded timecodes from the input source. Requires inputs with reliable embedded timecodes. See [Inputs must include embedded timecode (source timecode method)](./pipeline-locking-verify-input.html#pipeline-locking-embedded-tcode).

+     * **VIDEO_ALIGNMENT** : Uses visual signature comparison between encoders. Does not require embedded timecodes. See [Requirements for video aligned pipeline locking](./pipeline-locking-verify-input.html#pipeline-locking-video-alignment-inputs) for input compatibility.
