Issue Title: Synchronization of Stock-Related Checkboxes Between App Interfaces

1. Issue Description

There's a requirement to synchronize the "Maintain Stock" and "Allow Negative Stock" checkboxes between /app/item/ and /app/website-item/ in the Inventory tab. The checkboxes in /app/website-item/ should reflect the state of the corresponding checkboxes in /app/item/ and should be read-only to prevent direct modification.

2. Steps to Reproduce

1. Navigate to /app/item/ and locate the "Maintain Stock" and "Allow Negative Stock" checkboxes in the Inventory tab.
2. Change the state of these checkboxes (tick/untick).
3. Navigate to /app/website-item/ go to inventory tab and observe the state of the "Master Item: Maintained Stock" and "Master Item: Allow Negative Stock" checkboxes.
4. Confirm if the states are synchronized with /app/item/.

3. Current Behavior

• The state of the checkboxes in /app/website-item/ may not reflect the state of the corresponding checkboxes in /app/item/.

4. Expected Behavior

• The "Master Item: Maintained Stock" and "Master Item: Allow Negative Stock" checkboxes in /app/website-item/ should always be in sync with the "Maintain Stock" and "Allow Negative Stock" checkboxes in /app/item/.
• The checkboxes in /app/website-item/ should be read-only and not allow modification.

5. Action Items

• [ ] Review the current synchronization mechanism between the two sets of checkboxes.
• [ ] Update the synchronization logic to ensure that any changes in /app/item/ are reflected in /app/website-item/.
• [ ] Modify the permission settings for the checkboxes in /app/website-item/ to be read-only.
• [ ] Test the updated functionality to ensure synchronization works as expected and that checkboxes are correctly set as read-only.
• [ ] Document the changes made and update any related process documents.
