Improve Statsbomb case study readability and content flow

Content reorganization:
- Move Real-Time Collaboration before State Machines (better narrative flow)
- Remove repetitive diagram captions

Accordion improvements:
- Collapse optional sections: Quantitative/Qualitative Results, team history details, pattern applicability
- Add accordion margins (mb-6) for proper section spacing
- Wrap team member contributions in expandable accordions

Team section enhancements:
- Reorder chronologically (Waheed joined before Hadeel)
- Update Adham's role to emphasize Kafka architecture leadership
- Convert markdown bullets to semantic <ul> with Tailwind styling (list-disc ml-6 space-y-2)
- Fix typo: "Collobrated" → "Collaborated"

Result: Main narrative visible at a glance, details available on-demand, ~40% shorter page length
