Manual property enhancements: MLS status sync, agent clone, description formatting

- Manual properties linked to MLS now inherit status (Active/Pending/Closed) and
  days_on_market from the MLS listing dynamically
- Properties not in MLS default to Closed status
- Clone feature now auto-populates listing agent by matching MLS ID to Agent CPT
- Description formatter detects embedded headers (unpunctuated text after sentences)
  and splits them into separate paragraphs
