docs(P47): presentation slide updates + HIPAA removal from all docs

Presentation changes (both Marp decks + source markdown):
1. Title slide: deck title as H1 (slightly bigger), 'Agentic Cloud Delivery
   Platform' as H3 subtitle — cleaner title hierarchy
2. DX deck: removed Local Reproducibility slide (not beneficial for DX)
3. DX deck: Safe Promotion Path slide redesigned with side-by-side layout
   for Approaches A and B (HTML table, two columns)
4. DX deck: 'an agent' → 'an AI agent' (slide 2 + Citizen Developer slide)
5. DX deck: What a Developer Does — diagram floated to the right side
6. Header simplified to just the deck name (subtitle now on title slide)

HIPAA removal (25 files):
- Completely removed all HIPAA references from all markdown documentation,
  presentation source files, module READMEs, and rendered HTML
- Removed HIPAA from compliance milestone lists (GDPR, SOX, SOC2, DORA remain)
- Removed HIPAA section references (§164.xxx) from compliance annotations
- Cleaned up empty parentheses and broken commas left by removal
- Re-rendered both HTML decks from updated Marp source
