feat: Migrate Street and Task models from MongoDB to CouchDB

- Replace Street model with CouchDB-based implementation
- Replace Task model with CouchDB-based implementation
- Update routes to use new model interfaces
- Handle geospatial queries with CouchDB design documents
- Maintain adoption functionality and middleware
- Use denormalized document structure with embedded data
- Update test files to work with new models
- Ensure API compatibility while using CouchDB underneath
