feat: improve readability of list fields in CIM review

- Add normalizeToMarkdown() that converts inline "1) ... 2) ..." patterns
  to properly spaced markdown numbered lists for existing documents
- Update Zod schema descriptions to instruct LLM to use newline-separated
  numbered items in list fields (keyAttractions, potentialRisks, etc.)
- Fixes wall-of-text rendering in investment thesis and next steps sections
