Pull request overview

This PR focuses on fixing documentation build issues by correcting references and converting content into Sphinx/Doxygen-friendly formats, while also aligning several examples with snippet extraction markers used by the generated docs.

Changes:

• Fix/adjust documentation structure and formatting (Sphinx toctree entry, ADRC table formatting).
• Update Doxygen snippet references for RTSP packetizers/depicketizers and add snippet markers to examples.
• Minor docstring clarifications across a few components.
