Previously, in the `_isSublocation`, to check if a location was a children of another location, we did that:
```javascript
return childLocation.parent_path.includes(parentLocation.parent_path);
```
The issue with that is, if locations' id are aligned, they can match even if they are not related.

For example, imagine tested child location has ID 127 and the parent location has ID 7, we then check their `parent_path` (for example, '4/127/' for the child location and '7/' for the parent location), it can happen the child parent path can include the parent's parent path (in our example, '4/127/' includes '7/'.)

To fix that, this commit replaces `includes` with `indexOf`, the result of the `indexOf` should always be 0 if the child location is indeed a sublocation of the parent location.

Because of this issue, the second run of the tour `test_put_in_pack_new_lines` could sometime fail when the locations IDs are aligned.

When combo choices associated with products are deleted and
the user attempts to load sample data in the Furniture PoS, a traceback occurs.

Steps to reproduce the error:
- Install ``point_of_sale`` module without demo data
- Go to Point of Sale > Click on Furniture > Open Register > Load Sample > Close register
- Go to Point of Sale > Products > Combo choices > Delete all combo choices
- Go to Settings > Restrict Categories > Unset all categories > Save
- Go to Point of Sale > Dashboard > Furniture > Open Register > Load Sample

Traceback:
```py
ParseError: while parsing /home/odoo/src/odoo/19.0/addons/product/data/product_demo.xml:905
A combo product must contain at least 1 combo choice.
```

https://github.com/odoo/odoo/blob/c81e50d3b8f0ffc0297c97b06afd77e2c92ad508/addons/point_of_sale/models/pos_config.py#L1025
When clicking Load Sample button in the Furniture PoS,
the ``_load_onboarding_furniture_demo_data`` method loads the ``data/product_demo.xml`` file.
If the combo choices linked to products have been deleted,
loading the following record triggers the above traceback.

https://github.com/odoo/odoo/blob/c81e50d3b8f0ffc0297c97b06afd77e2c92ad508/addons/product/data/product_demo.xml#L664-L671

Solution:
Restrict deletion of combo choices if they are linked to any products.

The system will crash when user try to load sample data in appraisal.

**Steps to produce:-**
- Install `Appraisals` and `Recruitment` module.
- Make a new user with access right of administrator to `only Appraisals`.
- Login with new user.
- `Appraisals > Load sample data`.

**Error:-**
```py
AccessError: You are not allowed to create 'Job Position' (hr.job) records.

This operation is allowed for the following groups:
	- Recruitment/Officer: Manage all applicants

ParseError: while parsing /home/odoo/src/odoo/saas-18.4/addons/hr/data/scenarios/hr_scenario.xml:21, somewhere inside <record id="job_consultant" model="hr.job" forcecreate="1">

            <field name="no_of_recruitment">5</field>
            <field name="contract_type_id" ref="hr.contract_type_interim"/>
            <field name="description">We are currently looking for someone like that to join our Consultant team.</field>
        </record>

ValueError: ParseError('while parsing /home/odoo/src/odoo/saas-18.4/addons/hr/data/scenarios/hr_scenario.xml:21, somewhere inside\n<record id="job_consultant" model="hr.job" forcecreate="1">\n            <field name="name">Consultant</field>\n            <field name="no_of_recruitment">5</field>\n            <field name="contract_type_id" ref="hr.contract_type_interim"/>\n            <field name="description">We are currently looking for someone like that to join our Consultant team.</field>\n        </record>') while evaluating
'action = model._load_demo_data()'
```

**Root Cause:-**
- When a user is granted access rights only for the Appraisal module and attempts to load sample data for it, an error occurs. This happens because the sample data at [1] includes the `creation of records` related to the `Recruitment module`. Since the user does not have the required access rights for Recruitment, the system raises a permission error.

**Solution:-**
- In this commit, we resolve the issue by using `sudo()` while loading the data.

### Issue:
In a manual follow-up printed as PDF, overdue invoices appear twice.

### Step to reproduce:
- Create a partner and an overdue invoice for this partner,
- Send the invoice,
- go to this Partner then in the "Accounting" sheet,
- Choose follow-up as manual,
- Click on send,
- In the wizard select Print and "Join invoices"

### Current behavior:
The PDF display the reminder, the invoice, the report and the invoice again.

### Expected behavior:
Invoice should appear only once in the follow-up PDF.

### Cause :
When manually sending the follow-up, the wizard attaches the invoices to the follow-up. Then in `_get_followup_attachments`, it attaches the report, template attachments and the invoices again.
In a manual follow up, it should be possible to choose which invoices are sent. The method `_get_invoices_to_print` ensure this by looking at the options' attachment. Therefore, it's not possible to clear the attachment field before fetching the invoices.
