Finalize architecture design for TEEHR Evaluation-as-a-Service

[samlamont]

Provide a high-level design on how the user will interact with the data warehouse (remote and local) and components needed

[samlamont]

Perhaps some combination of transactional (postgresql) and analytics (iceberg).

• Postgresql: Caching ingests, calculated metrics for UI
• Data warehouse: Storing big data
• TEEHR-python: Client for accessing data warehouse
• Separate repo/toolset for ingest, postgres, UI code?
