[feat] python-databricks-sdk

[jrmcauliffe00]

Refactor main.py — use python databricks sdk instead of of requests library

# Initialize Databricks SDK client
def get_workspace_client() -> WorkspaceClient:
    """Create and return a Databricks WorkspaceClient"""
    if not all([DATABRICKS_HOST, DATABRICKS_TOKEN]):
        raise ValueError("Missing required Databricks credentials in .env file")
    
    return WorkspaceClient(
        host=f"https://{DATABRICKS_HOST}",
        token=DATABRICKS_TOKEN
    )
