**Issue**
Changing the workcenter of a workorder to another with a different time efficiency does not correctly update `date_finished`, causing the Gantt progress bar to show an incorrect expected duration.

**Steps to reproduce**
1. Create two workcenters marked as alternatives (100% and 50% efficiency).
2. Create a BOM operation that produces 100 products with a 1h expected duration each, on the 100% workcenter.
3. Create and plan an MO using this BOM.
4. In Planning > Planning by Workcenter (Gantt), drag the workorder to the 50% efficiency workcenter. → Expected duration remains 100h instead of 200h.
5. Drag the same workorder back to the 100% workcenter. → Expected duration becomes 200h instead of 100h.

**Cause**
`date_finished` is recomputed in `write()` using the *previous* workcenter’s efficiency, because the duration calculation happens before the new `workcenter_id` is applied: https://github.com/odoo/odoo/blob/18.0/addons/mrp/models/mrp_workorder.py#L471

Since the Gantt progress bar uses the interval [`[date_start, date_finished]`](https://github.com/odoo/enterprise/blob/18.0/mrp_workorder/models/mrp_workorder.py#L672C13-L674C107) to compute the expected duration (via `_web_gantt_progress_bar_workcenter_id`), the displayed duration becomes wrong.

***Behavior:***
In a setting with a second warehouse that is supplied by the first one. Creating a product that uses that ressuply route,
and then adding it to the bom of a kit product will make it so that when ordering the kit product to the second warehouse from the MPS, the system will create an order for an exponential amount of components.

When calling action_replenish, kit products for which the components don't have an MPS entry will have their product_ratio computed to know how many components to reorder. However the current formula is wrong or outdated and ends up returning the squared amount.

***Steps to reproduce:***
- Create a second warehouse.
- Check Resuply From 'First Warehouse' (this will unarchive a route)
- Create a product that uses that route for reordering.
- Create a second product
- Create a kit for that product BOM composed of the first product make sure the amount of component is more than 1
- In the Master Production Schedule: Add the kit product and make sure it is produced in the second warehouse with the unarchived route.
- Add any amount to reorder in 'Replenishment' then click the Order button.
- If you go to deliveries and look for your component, you'll see the amount of component per kit squared multiplied by the reordered kit amount.

Modules containing valid Markdown in their description or README.md could cause Odoo to crash during startup or module updates if the content confused the reStructuredText (RST) parser.

### Steps to reproduce

1. Create a module with a manifest like this:

    ```py
    {
        'name': 'base',
        'description': """
        ....
    """,
    }
    ```

2. Start the Odoo server or attempt to install or update update the module.
3. The server crashes:

    ```
    docutils.utils.SystemMessage: (SEVERE/4) Unexpected section title or transition.
    ```

### Cause

The crash occurs during the execution of the `_get_desc` method in the `ir.module.module` model, which computes the `description_html` field.

When Odoo processes a module, it checks for a pre-rendered HTML description at `static/description/index.html`. If this file is missing, the `_get_desc` method attempts to generate HTML from the module's `description` field (often populated from the `README.md` file) by calling the `docutils.core.publish_string` function.

The **docutils** library is designed specifically for **reStructuredText (RST)**. If the input text contains structural patterns that violate RST rules—such as inconsistent header levels or "transitions" in invalid contexts—docutils flags a severe error and raises a `docutils.utils.SystemMessage` exception.

### Fix

This commit handles these exceptions and falls back to a raw text rendering. It also improves the logic by removing the restriction that prevented non-application modules from rendering their description via RST.

Steps to reproduce:
-------------------
1. Enable cash rounding, only for cash payment method
   - Rounding method doesn't matter, I tested with 0.05 nearest rounding
2. In PoS, make an order with the customer account, such that the total amount is not divisible by 0.05, i.e. when rounded, it's not the same amount. For instance, $5.27.
3. Close the session and reopen it, then select that customer, and click settle due
4. Select the Bank payment method, so a NON-Cash payment method.

Notice that the amount is being rounded, even though we have only enable rounding for cash methods. If we take my example of step 2, the amount became $5.25 instead of $5.27.

That is understandable when we settle with Cash, however, for Bank (non-cash), we should not round.

The fix
-------
Now when choosing a payment method to settle due, we also round the amount if needed, in `getTotalDueOfPartner`. Before, we always set the exact amount, regardless of the payment method and the rounding settings.

We now also apply rounding on the payment screen based on the selected payment method. Previously, the change was always rounded whenever rounding was enabled, ignoring whether rounding was restricted to cash methods. This behavior made sense for normal orders—where change is typically given in cash—but not when settling a due amount, since the customer can pay using any method. During due settlement, the change represents the amount the customer must pay, so rounding must follow the rules of the chosen payment method.
