[MOV] move sale_payment into sale
=================================

Almost all use cases of sale require sale_payment down the line.

There is only one case which does not: using sale_management without website_sale or website_quote.

However, since we want to move most of the features of website_quote into sale_management, moving sale_payement first will make the task easier.

[MOV] move website_quote into sale and sale_management
======================================================

We want to use some features of website_quote without having to install the whole module.

The main issue with website_quote was that it had a requirement on website.

What is common to website_sale and sale_management has been moved into sale. This is primarily the sales order portal view.

What is only related to sale_management has been moved into it. This is notably: sales order templates, optional products, sign and pay, ...

Everything that requires website has been moved into a new module named sale_quotation_builder. This is related to using the HTML builder to customize the quotation view.

Models, files and routes have been renamed to better convey their purpose and to follow guidelines more closely.

[IMP] merge sales order portal views
====================================

The old sales order view on the portal has been merged into the one from website_quote. The new view contains features of the two.

A lot of fixes and improvements have also been done, related to BS4 issues but also to improve the sales order view in general.

[IMP] add new settings
======================

The commit adds new settings related to activating the features that previously were activated by installing website_quote.

Website quote gave the possibility to define an email template to use
when sending a quotation / sale order by email. This was done at a time
where doing correct templates in sale was difficult to do / implement.
Now send by email template is completely inside sale module and should
cover all use cases.

Having a settings to customize it is not considered as necessary as it
can be customized easily.

This commit is linked to task ID 1843171 (and 1868112) and to PR #25293
(and #25889).

We also:
- reorder a bit the form view for quote templates
- change the way default templates are selected for sales order
  (inactive quote templates are not selected) while keeping
  customizability through ir.values

Using a real ir.values default that user can customize in settings
is better for user experience than an hardcoded template using an
xml_id. Betcha.
