**Steps to reproduce:**

1. Install the Accounting module.
2. For partner X, create minimum 90 invoices for `See more/Load more` option into page.
3. In the partner form view, click the Customer Statement smart button.
4. Change the Report Type from Customer Statement to Follow-Up Report.
5. In the report, click `See more` in the dropdown → traceback occurs.

**NOTE**
-  You can easily create invoices using this cron job to generate 90 invoices.
```py
for i in range(90):
    invoice = env['account.move'].create({
        'move_type': 'out_invoice',
        'partner_id': 10,
        'company_id': env.company.id,
        'invoice_line_ids': [(0, 0, {
            'product_id': 16,
            'quantity': 1,
            'price_unit': 100.0,
        })],
    })
    invoice.action_post()
```

 **Issue:** 

`UncaughtPromiseError > OwlError
Uncaught Promise > Got duplicate key in t-foreach: ~account.report~17|~res.partner~42|Due~~
Occured`
- A traceback occurs due to a duplicate key error.

 **Cause:** https://github.com/odoo/enterprise/blob/459e8ddaf6f67a556d35bf00e0fbb68eb1500a94/account_reports/static/src/components/account_report/account_report.xml#L72-L73

- In account_report.xml component uses line.id as a key.

- When expanding `See more` headings like `Overdue` are rendered again with the same ID causing a duplicate key error.

**Solution:**
- Use the `line_index` instead of `line.id` as the key, ensuring a unique key for every line and preventing the traceback.

**Issue**
When the delivered quantity of a product is less than the originally demanded quantity, the generated Delivery Guide XML shows the demand (product_uom_qty) instead of the actual delivered quantity (quantity). This results in an incorrect quantity being displayed in the DTE.

**Steps to Reproduce**
1. Install the Accounting module, Chilean localization, Sales module, and l10n_cl_edi_stock.
2. Create and confirm a new Sale Order.
3. Click on the Delivery smart button.
4. Adjust the delivered quantity to a value lower than the demand, save, and validate with no backorder.
5. Generate the Delivery Guide.
6. Open the generated DTE XML and observe that the quantity is incorrect.

**Root Cause**
The quantity displayed in the DTE is taken from product_uom_qty, which represents the planned quantity to be moved, not the actual delivered quantity. The correct field to use is quantity, which reflects the real delivered amount.

**Fix**
Change the XML output to use quantity instead of product_uom_qty to accurately reflect the actual delivered quantity in the DTE.

Issue
-----
When using Shiprocket with the "Cash On Delivery", the request sent to the Shiprocket API doesn't contain the amounts discounted by coupons.

Steps to reproduce
-----
- Set an Indian company up (with valid address and some dummy mail & phone)
- Create a customer "IN Cust" (with valid address and some dummy mail & phone)
- Create a product "IN Prod"
	- Sale price: 1000 INR
	- Weight: 100g
	- Set some reference, eg "INPROD"
- Create a Shiprocket delivery method
	- Payment Method: COD
	- Set some "Shiprocket Channel"
	- Enable Debug requests
- In settings, enable "Promotions, Loyalty & Gift Card"
- Go to Sales > Products > Discount & Loyalty
- Create a new program
	- Name: 50% off
	- Program Type: Coupons
	- Change the existing reward to 50% discount on order
	- Generate some coupon
	- Copy the code of the generated coupon
- Create a SO our product and customer
- Use the coupon code & apply the 50% discount
- Add shipping
	- Shiprocket COD
	- Get rate
- Confirm the SO
- Go to the picking & validate it
- Open logs (Settings/Technical/Database Structure/Logging)
- Open the "shiprocket_request_external/shipments/create/forward-shipment" log

--> total_discount is 0

Cause
-----
The problem comes from

https://github.com/odoo/enterprise/blob/a971f55e736f9645eda137fd6dcb574483886483/delivery_shiprocket/models/shiprocket_request.py#L301

There are 2 issues here.

The first and most important one is how we find the discount lines.

https://github.com/odoo/enterprise/blob/a971f55e736f9645eda137fd6dcb574483886483/delivery_shiprocket/models/shiprocket_request.py#L320

Discounts from coupons don't use the `sale_discount_product_id`. We can use the `_can_be_invoiced_alone` function to find both regular and loyalty discounts

https://github.com/odoo/odoo/blob/ee63fe7863dfa0083674dc927c1aa67c9e36c481/addons/sale/models/sale_order_line.py#L1033-L1041
 
    def _can_be_invoiced_alone(self):
        """ Whether a given line is meaningful to invoice alone.

        It is generally meaningless/confusing or even wrong to invoice some specific SOlines
        (delivery, discounts, rewards, ...) without others, unless they are the only left to invoice
        in the SO.
        """
        self.ensure_one()
        return self.product_id.id != self.company_id.sale_discount_product_id.id

https://github.com/odoo/odoo/blob/ee63fe7863dfa0083674dc927c1aa67c9e36c481/addons/sale_loyalty/models/sale_order_line.py#L50-L51

    def _can_be_invoiced_alone(self):
        return super()._can_be_invoiced_alone() and not self.is_reward_line

We just have to be careful not to accidentally include delivery fees because of

https://github.com/odoo/odoo/blob/ee63fe7863dfa0083674dc927c1aa67c9e36c481/addons/delivery/models/sale_order_line.py#L18-L19

    def _can_be_invoiced_alone(self):
        return super()._can_be_invoiced_alone() and not self.is_delivery

The second issue is that we use the untaxed discount amount.

https://github.com/odoo/enterprise/blob/a971f55e736f9645eda137fd6dcb574483886483/delivery_shiprocket/models/shiprocket_request.py#L321

This leads to an incoherent total amount, since the tax is computed on the products' full prices. We should instead be forwarding the total discount value (with tax included to offset the taxes applied on the full product price).
