presentation.org: back to original H:1 + renewenvironment{frame}

H:2 was my mistake — broke frame titles and content splitting.
With H:1 (default): * = frame, ** = content inside frame.
allowframebreaks auto-splits long frames (Domains I, II, III...).

This is the ORIGINAL working template + only Kyndryl colors added.
No other changes to layout/frame/table logic.
