DuckLake Migration

[FWJK1]

• Migrate storage to DuckLake throughout codebase.
• Use Medallion Architecture, where we store the unprocessed data under a different name, eg raw_zoning, and then the cleaned under a format like clean_zoning_rules. For now, I think just raw and cleaned is sufficient
• Provide design doc on decisions made through process and how this will affect future work.
