Problem: When both line discounts and global discounts are applied on a product in an invoice, the method `_add_and_round_raw_gross_total_excluded_and_discount` does not return the exact raw_gross_total_excluded before the modification done by other AccountTax helper methods, such as dispatching and squashing global discount lines.

Current Behavior: The calculation is done in the wrong order of operations. For example, there is an invoice for Product A valued at $100 with a discount of 10% and a global discount of $10. The raw_total_excluded will be $80 after the both discounts. The discount_factor is based on only the line discount of 10%. The formula of the current calculation for raw_gross_total_excluded is: (raw_total_excluded / (1 - (line_discount / 100))) - global_discount = (80 / 0.90) - (-10)
= 98.889
This does not equal the expected outcome of $100.

Expected Behavior: Based on the previous example, the formula for the calculation should be:
(raw_total_excluded - global_discount) / (1 - (line_discount/100)) = (80 - (-10)) / 0.9
= 100
The global discount needs to be added back to the raw_total_excluded to get the line discounted amount in order to divide by the discount_factor to gain the expected raw_gross_total_excluded before taxes and discounts.

Steps to reproduce the issue:
- Bug was encountered when implementing a global discount solution for l10n_co_dian.
- Create an invoice with a product line and in-line discount and another line for global discount
- Setup the base lines for the invoice and attempt the following:
 - _dispatch_global_discount_lines
 - _squash_global_discount_lines
 - _add_and_round_raw_gross_total_excluded_and_discount

When having an horizontal group with domain including two companies that
share the same account codes, report lines with account codes engine
don't display the two companies values when both are selected in the
company selector.

Steps to reproduce:

- Install l10n_ch and create two CH companies (CH1 and CH2)
- Create an horizontal group with the field 'Company' and domain '["|",
  ("name", "=", "CH Company"), ("name", "=", "CH 2")]"
- Apply the Horizontal group to CH balance sheet report
- Select both companies in the company selector
- Open CH BS report and activate the horizontal group
-> Only the column of one company is filled

Fix:

https://github.com/odoo/enterprise/commit/9b775ed9d8b2a18e708219c72e95652571f3936a
was introduced in 19.0 to fix the same issue, we fix by backporting it
but we also need to backport this perf commit https://github.com/odoo/enterprise/commit/7da3123dc4487a7092deef8503a9791ceffddcfb
that refactored the code before in a first place

France’s electronic invoicing reform : The tax administration  needs structured fiscal data for the transactions , either via E-invoicing for the nationals B2B or E-reporting for the international B2B and the B2C.

This creates two complementary obligations:

- **E-invoicing** for domestic B2B transactions, where the invoice itself is exchanged through the PA/Peppol flow.
- **E-reporting** for transactions outside that domestic B2B scope, mainly B2C and international B2B, where transaction and payment data must be reported to the tax administration through Flux 10 (period-based).

## Scope

Domestic B2B remains handled by the existing e-invoicing flow, because the invoice exchange already carries the required structured information.

Flux 10 is introduced for transactions that must be reported separately:

- B2C transactions, where there is no buyer-side e-invoice exchange.
- International B2B transactions, where the counterparty is outside the French domestic B2B mandate.
- Payment reporting when VAT exigibility depends on collection.

The reporting is period-based and keeps transaction reports separated from payment reports, because they answer different legal obligations and follow different timelines.

## Corrections and Lifecycle

Flux 10 supports both:

- **Initial reports**, for the first declaration of a period.
- **Rectificative reports**, when already reported data must be corrected or completed.

This distinction is needed so corrections remain traceable instead of silently mutating a report that may already have been transmitted.

## Security and Eligibility

This PR also enforces stronger safeguards before using PDP/PA services.

- **2FA is required** because PDP/PA actions expose regulated fiscal flows and should not be available from a simple password-only login. Email-based 2FA is available as a fallback when users have not configured an authenticator app.
- **KYC is introduced** because a company must be identified and validated before Odoo can transmit documents or reports on its behalf through the PDP/PA infrastructure.

Together, these changes make the French PDP/PA flow usable not only for invoice exchange, but also for the wider e-reporting obligations required by the French reform.


Task-4603708

Steps to reproduce:
-------------------
1. Install `sale_project_stock` and Accounting.
2. Create a storable product with **Real-time valuation** and 
configure the COGS account in the product category expense account.
(Ensure you have enabled automatic & analytic accounting from accounting>config.)
3. Create a project with a specific analytic account and ensure the project is billable.
4. Create a sale order with the created product and set the same
analytic account in the analytic distribution.
5. Confirm the order, deliver the product, generate the invoice, and post it.
6. Open the project and go to the *Profitability* report.
7. Click on the **Cost of Goods Sold** dashboard item.
8. Repeat steps 4–7 with multiple invoices.

Issue:
------
When there is only one invoice, clicking the COGS dashboard item correctly
displays the related move lines. However, when there are multiple invoices,
the action opens with empty results.

Cause:
------
`_get_action_for_profitability_section` sets `res_id` only when a single record exists. 
When multiple records are present, `res_id` becomes `False`, which causes the action to open without results. https://github.com/odoo/odoo/blob/8f79d407724f40ba8e48f1747b2e87311b7fb49e/addons/project_account/models/project_project.py#L78-L83

Solution:
---------
When `res_id` is not set, search `account.move` records using the
domain to retrieve the relevant move IDs, then apply a proper domain
to display all related COGS journal items.
