### Steps to Reproduce:
1. In Debug mode, go to Aliases
2. Click on any active Alias, ex. customer-care
3. Click on "Open Parent Document" smart button
4. Click on "Tickets" smart button and observe error

### Description of the issue/feature this PR addresses:
**Issue:** When navigating from an email alias to its parent document (e.g., a Helpdesk Team), the web client incorrectly retains the  `active_id` and `active_model` of the alias in the context.

**Solution:** We updated the `action_view_ticket` method in `helpdesk.team` to explicitly inject the correct `active_model` and `active_id` into  the context before calling `_for_xml_id`. This overwrites the polluted Alias data before the window action is evaluated.

### Current behavior before PR:
Clicking the "Tickets" smart button passes the old alias context into the action. This bad data flows into the ticket view, which attempts to look up a Helpdesk Team using the Alias's ID to generate the empty list help message, resulting in a `MissingError`.

### Desired behavior after PR: 
The Python action sanitizes the context at the source, ensuring that the XML action and subsequent view evaluations receive the correct Helpdesk Team ID. Ultimately, the view will load normally without crashing.

Steps to reproduce:
- Create a sale order with a down payment term.
- Invoice the down payment (down payment invoice A).
- Credit that down payment invoice directly (credit note A), without reconciling it with anything else.
- Generate the FatturaPA XML for credit note A.
- Observe that DatiFattureCollegate lists both down payment invoice A and credit note A itself, instead of only down payment invoice A. On an order with several down payment invoices/credit notes over time, every one of them is listed instead of just the document the current credit note actually reverses.

Cause of the issue:
_l10n_it_edi_export_data built downpayment_moves from self.invoice_line_ids._get_downpayment_lines().move_id with no filtering. _get_downpayment_lines() (sale override) returns every invoice line ever created against the same down payment sale order line, across the whole life of the order, not just the invoice the current document actually relates to. The template renders DatiFattureCollegate for every one of those moves unconditionally, on top of the already-correct reversed_entry_id/reconciled_moves fallback, including the current document itself.

Solution:
Restrict downpayment_moves to lines with a negative price_subtotal, mirroring the existing down payment deduction-line detection a few lines above, and explicitly exclude the current document. This limits DatiFattureCollegate's down payment entries to the case they are meant for: a final invoice actually deducting a previously invoiced down payment.

Steps to produce:
---
- Create a company with `Argentina` as the country.
- Switch to the newly created company.
- Create a new website for the `Argentina company`.
- Create a pricelist with a `23%` discount on the sales price for all products.
- Create a new product, set the sale price to 100, remove all tax, and publish.
- Go to the website and switch to the newly created Argentina company website.
- Go to the Shop page and open the product.

Issue:
---
- The tax-excluded price (`Precio s/Imp. Nac.`) displayed on the shop catalog card differs from the tax-excluded price displayed on the product detail page.

Root cause:
---
- In `_get_additionnal_combination_info`, [1] returns the unit price with the pricelist discount already applied. However, when `combination_info['has_discounted_price']` [2] is `True`, the method applies the discount again manually, resulting in the pricelist discount being applied twice on the product detail page.

Solution:
---
- Remove the redundant discount calculation block. This ensures that the tax-excluded price displayed on the product detail page matches the price shown on the shop catalog card.
