fix: make provider switching work by setting attributes on SecretStrInput for Agent Component Inputs (#4643)

* Refactor `process_inputs` function to handle `SecretStrInput`

- Reset `value` and disable `load_from_db` for `SecretStrInput` instances.

* [autofix.ci] apply automated fixes

* Update model_input_constants.py

Optimize input processing for speed improvements
