* refactor: enhance database session management in custom components
- Updated `get_variables` method in `CustomComponent` to accept an optional session parameter, allowing for session reuse and reducing connection pool exhaustion.
- Modified `update_params_with_load_from_db_fields` to pass the session when calling `get_variables`.
- Adjusted `get_instance_results` to support session management for database operations.
- Increased connection pool size and max overflow in settings for improved performance under load.
* [autofix.ci] apply automated fixes
* Prefer single session by default:
* remove unused session
* Revert pool size changes
* refactor: update get_variables method for backward compatibility
- Added a new async `get_variables` method in `CustomComponent` to maintain backward compatibility with the deprecated method, ensuring it calls the existing `get_variable` method with session management.
- This change enhances the robustness of the component while preserving existing functionality.
* refactor: remove unused session import from endpoints.py
- Eliminated the unused `session_scope` import from the `endpoints.py` file to streamline the code and improve clarity. This change contributes to maintaining a clean and efficient codebase.
* refactor: update deprecated variables method in CustomComponent
- Modified the `variables` method to call the new `get_variables` method for improved clarity and consistency. This change maintains backward compatibility while encouraging the use of the updated async method.
* refactor: update method calls to use get_variables because we don't have session in update_build_config
- Replaced instances of the deprecated `get_variable` method with the new `get_variables` method in `LMStudioEmbeddingsComponent`, `LMStudioModelComponent`, and `ChatOllamaComponent`. This change enhances code clarity and maintains consistency across components while ensuring backward compatibility.
