Currently, when a user deletes a line and validates internal movement in the barcode system, the system allows validation even though specifying the destination location after each scan is required.

## Steps to produce:
- Install the Inventory module
- Go to Settings and enable Storage Locations.
- Inventory > Configuration > Operation Types > Internal Transfers > Barcode App
- Configure the Destination Location to require scanning after each product.
- Create an Internal Transfer for Pedal Bin, demand 1.
- Mark the transfer as To Do and open it in the Barcode app.
- Add quantity using +1, then scan the barcode for the Pedal Bin(Barcode: 6016478556493).
- Delete the newly added line and attempt to Validate.

## Observed Behavior:
The system should prevent transfer validation when the destination location has not been scanned and display a notification to the user, similar to the behavior before user deleted the newly added line.

## Root cause:
This issue occurs because when the delete button is pressed, the deleteLine function [1] removes the line, but the deleted line becomes the selected line due to [2] being triggered before the UI updates.

As a result, the selected line is now undefined. Since the selected line is undefined, it fails to meet the condition at [3] during validation. This prevents notifications from being triggered and allows the transfer to be validated before the destination location has been scanned.

## Solution:
We can prevent users from validating if any line has an unscanned destination location when destination-location scanning is mandatory after scanning each product.

To enforce this behavior, we can track whether a line has been modified and whether a destination location has been scanned and applied to that line. This allows us to identify which lines still require destination location scanning before validation can proceed.

However, line state information is currently discarded and recreated on every save. As a result, information about lines that were updated and already had their destination location scanned is lost. This may incorrectly require users to rescan the destination location, even though it was previously scanned.

To address this, we preserve the destination-scanned and modified state by carrying it forward from existing lines to their corresponding newly created versions using a loop. This ensures that destination location scan status is retained and users are not asked to rescan unnecessarily.

Currently, an error occurs when user tries to select a property field in auto field.

Steps to replicate:
- Install `sale_management` and `sign`.
- Open Sales > Products > Products > Open any product.
- From the Gear icon, Click Edit Properties and save the record.
- Enable Debug mode if you are using a version lower than 19.0 .
- Open Sign > Configuration > Field Types.
- Create a new Field > Give a name > Select model as `Product`.
- Select Field as `Property > Property 1` and click save.

Error:
- saas-18.3 and later:
```
  File '/home/odoo/odoo18/enterprise/sign/models/sign_item_type.py', line 57, in _check_auto_field_exists
    auto_field_value = record.mapped(sign_type.auto_field)
                       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File '/home/odoo/odoo18/community/odoo/orm/models.py', line 5472, in mapped
    field = records._fields[field_name]
            ^^^^^^^^^^^^^^^
AttributeError: 'Property' object has no attribute '_fields'. Did you mean: 'field'?
```

- saas-18.2:
```
  File '/home/odoo/odoo18/enterprise/sign/models/sign_item_type.py, line 41, in _check_auto_field_exists
    auto_field_value = record.mapped(sign_type.auto_field)
                       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File '/home/odoo/odoo18/community/odoo/orm/models.py', line 5744, in mapped
    if len(records) > PREFETCH_MAX:
       ^^^^^^^^^^^^
TypeError: object of type 'bool' has no len()
```

Cause:
- As the user gave auto fill field as a Property field the [line] called `mapped()` to access its value, this caused the error to occur.

- This occurs because `mapped()` expects a `recordset` (models.Model), but instead it receives a Property object, which does not have `_fields`.

Solution:
- Using `'allow_properties': 'False'`, the property fields wont appear in the list of field selection.
