Refactor imports and add fields to OllamaStructuredResult

Reorders and deduplicates import statements across multiple files for consistency and clarity. Adds additional fields to OllamaStructuredResult and ensures OllamaResult is populated with these fields. Updates tests and minor code style improvements throughout the codebase.
