Enhance error handling and state management in access card and session modules

- Updated the `render_access_panel` function to conditionally hide LLM errors when the Ollama model is operational, improving user experience by reducing unnecessary error visibility.
- Introduced a new `_notes_from_disk` function to streamline the retrieval of notes from disk, enhancing state management during GPU environment checks.
- Refactored error handling in the `_bind_access` function to ensure that stack and GPU environment errors are accurately recorded and managed, improving robustness in session state updates.
- Added tests to validate the new behavior of error handling and state management, ensuring that LLM errors are appropriately suppressed when conditions are met.
