NF-e invoices can optionally include sent packages. This integrates with the stock module to provide a way for users to specify packages on invoices.

Typically EDI is done before products are sent out ("ordered quantity" invoicing policy). To handle this the user can enable 2-step picking. In the first step they can record how they will package the products. After that, the packages can be included on the invoice for EDI. At a later time products can be delivered to the customer in the last step. We provide a picking smart button in the invoice form view to easily navigate to the related pickings to sort out the packaging. This is typically done by a dedicated person who handles everything related to EDI.

Note that for products to be included in packages they must be storable (is_storable). The stock module allows to package
non-storable products as well, but in those cases the resulting stock.quant.package's are empty (no quant_ids).

## TODO
- [ ] translations

Steps to Reproduce:
===================
- Open a POS session and go offline.
- Create orders and print receipts at the receipt screen.
- Restore the internet connection and bring the POS online.
- A traceback occurs during synchronization.

Before this commit:
=====================
A traceback occurred when making a POS order, printing a receipt in offline
mode, and later going online.
The issue arose because the nb_print field was updated via a backend write call
to restrict payment method edits. However, during offline mode, the order_id
was a string, causing the traceback.

After this commit:
===================
- The backend write call for nb_print is bypassed in offline mode. Instead, the
 `nb_print` count is updated on the frontend. When the order syncs after going
  online, the increased `nb_print` value prevents payment method edits as
  expected.
- Removed the nb_print validation constrains from payment lines. Validation is
  already handled in the write method of pos.order. This change avoids
  validation errors when syncing orders from offline to online, where
  nb_print = 1 and payment lines exist. The write method ensures proper handling
  during order creation.
- A `Connection Lost` error message is displayed when attempting to send
  orders to the kitchen while in offline mode.

When Lot valuation is enabled on a product, it is not longer possible to create a move without lot. Hence, if you had a valued quantity without lot before enabling lot valuation, it was impossible to update or empty this quantity in any way. Leaving you with an unusable StockQuant. Furthermore, when enabling the lot valuation, no layer was created for the quants without lot, creating a permanent discrepancy between the stock and valuation. This discrepancy was still present even after disabling the lot valuation.

To fix this issue, we do not allow the lot valuation if there is a quant without lot in a valued location.

Email clients have begun implementing security measures to protect
users from phishing by analyzing email links, and interacting with
them (see task-3972953).

This has the side effect of automatically unsubscribing email
recipients from mailing lists by clicking the link in the footer of
the emails.

This commit adds an intermediate step to the process, by requiring
users to click on a button before they are unsubscribed.

task-4364446

--

The current unsubscription destination page for emails makes it unclear
for the user whether they've been unsubscribed or not.

This is because the "unsubscription confirmed" box is placed below the
"manage subscription settings" box on the confirmation page.

To avoid confusion, while ensuring current Studio customizations to
stable instances are not impacted, a new intercalate page is added
to clarify that the user is unsubscribed, and offer the option
to manage unsubscriptions by reaching the previous page.
