fix: Reset related fields on input mode change in Sales Order page

- Updated the input mode selection logic to clear associated fields (partner_id, delivery_partner_id, delivery_address) when the input mode changes.
- This change ensures that the form state is correctly managed and prevents stale data from being retained, enhancing the user experience across multiple companies.

These modifications aim to improve the clarity and functionality of the Sales Order page by ensuring that changes in input mode reflect accurately in the form state.
