Bug/document linking (#688)

* feat: enhance supplier invoice payment process and settings handling

- Implemented linking of invoice documents to journal entries for cash payments in the supplier invoice payment process.
- Refactored settings fetching logic to improve loading states and error handling across various settings components.
- Introduced a new SettingsLoadError component to handle cases where settings fetch fails or returns no data.
- Updated useSettings hook to manage loading and error states more effectively, allowing for retries on failure.
- Enhanced tests for supplier invoice creation to ensure document IDs are persisted correctly for cash method payments.

* feat(salary): enable monthly salary edits in draft runs and handle zero-total declarations
