docs: update to supported formats

[PiotrKorkus]

• Markdown files were not included in documentation and not rendered anywhere
• Relative links markdown files were reporting errors in docs_combo_build in reference_integration
• .uxf is not supported by sphinx-needs

Please double check diagrams, as I used AI to convert them into PlantUML and they were not rendered anywhere for comparison.
