Refactor deeply nested lists in bizdevbible.md for better readability

Converted 4-5 level nested lists into clearer hierarchical structure using
section headings and bold text. This improves scannability and maintainability
while preserving all original content.

Changes:
- Polkadot Cloud section: Added "High-Volume Businesses" and "Custom Web3 Solutions" headings
- Polkadot Hub onboarding: Organized into clear categories with level-4 headings
- Polkadot Hub limitations: Restructured into "Large Scale Operations" and "Advanced Customization Needs"

The refactored structure reduces cognitive load and makes the document easier to navigate.
