Currently, when the user creates a task for a customer with a discount pricelist, the discount is applied twice for the service.

<h2>Steps to produce:</h2>

* Install `industry_fsm_sale` and enable `Discounts` and `Pricelists` in settings.
* Create a pricelist with a price rule of type discount that applies 10 percent discount to every product.
* Go to Customers > Acme Corporation > Sales & Purchase and set the pricelist.
* Go to Field Service > Create a Task, and set `Customer` to Acme Corporation.
* Add a timesheet with Time Spent 1 > Mark the task as Done > Sale Order

<h2>Observed behavior:</h2>

The discount is applied twice to the product on SO:

**Product**: Service on Timesheets
**Unit Price**: `$40` (excluding tax)

**First discount:**
The 10 percent discount on the unit price of the product.
Product unit price is set from  `$40 -> $36
`

**Second discount:**
The 10 percent discount on the SO line itself.
`$36 -> $32.4
`

The untaxed amount is: `$32.40` which should be `$36.00`

<h2>Root cause:</h2>
This happens because, at line [1], the unit price is already set to the final price from the pricelist when the sale order line is created. Since discounts are enabled, [2] applies an additional discount to that same price, causing the discount to be applied twice.

<h2>Solution:</h2>

When creating the sales order:
* **Discount setting is on:** use list price so the discount is applied from the sales order.
* **Discount setting is off:** set the product unit price to the discounted price.

## Issue Before This PR:
When navigating from the Barcode client action
(e.g. picking, inventory, etc.) to related form views
(such as lot, product, or company), the breadcrumb
would sometimes display an unnamed entry instead
of the originating document name.
This caused confusion for users, as they could not
easily identify which document they were coming from
when navigating to related records from the Barcode interface.

## Steps to Reproduce:
- Install the Barcode module.
- Open the Barcode app and navigate to:
     - Delivery Orders.
     - Manufacturing Orders
     - Batch Pickings
     - Inventory Count
- From any of these open a record
  (e.g. picking, MO, batch, inventory line)
- Click on document name or edit button on the line.
- Click on an external link (e.g. product, lot, company).
- Observe that the breadcrumb shows an unnamed entry.

## Cause of the Issue:
- When switching views inside the Barcode client action,
  the FormController calls `setDisplayName(this.displayName())`.
  In some cases, this returns an empty string, overwriting the
  previously set breadcrumb name.
- In several form views, the `display_name` field was not present,
  preventing the controller from retrieving a proper name.

## With This PR:
The Barcode views now display the correct document names in the
breadcrumb when navigating to external links, allowing users to easily
identify the originating document when opening related records from
the Barcode app.

Currently, an error occurs on clicking on the graph or the pivot cell if the data is grouped by Employee/Manager/Department.

### **Steps to reproduce**
1) Install helpdesk_timesheet with demo data
2) Go to Timesheet > Reporting > Ticket Analysis
3) Set group by to Employee
4) Click on any graph bar or pivot cell

### **Error:**
`ValueError: Invalid field helpdesk.ticket.employee_id in condition ('employee_id', '=', 1)`

Root Cause:
The `helpdesk.ticket.report.analysis` model includes specific fields such as `employee_id`, `department_id`, and `employee_parent_id` (see [1]) that are defined for reporting purposes but do not exist on the `helpdesk.ticket` model. When a user clicks a data point to view related tickets, the reporting view passes the current domain directly to the ticket list view. Because `helpdesk.ticket` lacks these fields, the ORM fails to validate the domain, resulting in a server error.

### **Fix:**
This commit introduces a mixin to intercept the openView call. The mixin maps reporting-specific fields to valid relational paths on the ticket model `(for example, employee_id is transformed into user_id.employee_id)`. This ensures that the domain generated from the report model is compatible with the target ticket model.
