This fixes a regression with 445e8fa8 (ERP5TypeTestCase: rework
default manager password generation, 2024-05-27), it was no longer
possible to run live tests from a "normal" zope instance, this was
failing with:

Traceback (most recent call last):
  File "./eggs/Zope-5.10-py3.9.egg/Testing/ZopeTestCase/PortalTestCase.py", line 59, in setUp
    self._setup()
  File "./parts/erp5/product/ERP5Type/tests/ERP5TypeLiveTestCase.py", line 156, in _setup
    self.login()
  File "./parts/erp5/product/ERP5Type/tests/ERP5TypeTestCase.py", line 290, in login
    return PortalTestCase.login(self, user_name)
  File "./eggs/Zope-5.10-py3.9.egg/Testing/ZopeTestCase/PortalTestCase.py", line 146, in login
    user = user.__of__(uf)
AttributeError: 'NoneType' object has no attribute '__of__'

It was only possible from a runUnitTest instance.

Also: add `getTotalQuantity`. Why?

…and delete unused `z_catalog_stock_list_without_delete_for_inventory_virtual_movement`

In order to have Inventory Offset Lines, we want the user to be able to check
the generated lines before validating. This commit therefore adds an
intermediate state `planned`, which will be used to trigger generation of
Simulation Movements and building of the offset lines.

Some other small changes have been done to make the actions' names more clear
and adhere to ERP5 standards, but all keep backward compatiblity: previous states
have been kept, and previously validated inventories are now recorded so that
no Simulation Movements will be generated that would impact stock values.

   The script is supposed to be called on portal context (or any context) and not on MailevaSOAPConnector, and it should return a MailevaSOAPConnector for a given reference.

    In the implementation where the user cannot directly insert holidays (by an specialised role/implementation) it allow the accountant insert the values more easily. Using a simple action.

    Add simple jump for navigate to the holidays/leave

  This helps to review value on the print out

Fix UI tests error introduced by f159d4f2. As it checks for timeout,
simulation finished state cannot be reached anymore.

Fix projection by not making a square map from non square limits (width != depth).
This way rotation does not result anymore in deformed shapes (it was the case until now because proportionality was not respected between width and depth).

Fix typo (cbe50b0f): erp5_accounting_l10n_fr: the French Fiscal Report (FEC) can be generated for different ledgers.

WebSection.getDocumentValueList() returns absolutely all the documents (as catalog brains) reachable by the web section. Then, calling .getUid() on them load all the objects in memory. The number of documents is of the order of hundreds, even on a small ERP5 (web pages, web scripts, etc.).

Limit the documents to retrieve in WebSection_getLatestDiscussionPostList by filtering on the portal_type, and do not load them needlessly in memory.

  This aims to add compatibility with BTreeFolder2 API, even it is not
  required. Since some checkConsistency may call self._cleanup() regardless
  expecting that the folder is a [H]BTreeFolder2 always.

  This was detected when a post upgrade constrant was included to
  portal_categories

The methods used in indexing did not make a difference between the case
where the price is None (ie. price is not set) or where the price is
set to 0 - in both cases this was saved as NULL in stock.total_price
column. This is incorrect, we need to keep the distinction between
these two cases also for inventory calculation.
We had some places where we select IFNULL(stock.total_price, 0) to work
around this, we don't plan to change the existing ones for now, but
while discussing on nexedi/erp5!1974
we concluded that a newly idenfified case of a problem consequence of
these NULL should be handled by fixing the indexation. To benefit from
the fix, impacted instances will have to reindex documents present in
the stock table with stock.total_price is null.

__import__ `fromlist` argument was wrong. It was working anyway with Python2 but
not anymore with Python3, raising a `ModuleNotFoundError` exception. According
to Python `__import__(name, globals, locals, fromlist)` documentation:

  When the `name` variable is of the form `package.module`, normally, the
  top-level package (the `name` up till the first dot) is returned, *not* the
  module named by `name`. However, when a non-empty `fromlist` argument is
  given, the module named by `name` is returned.

Thus, the following patterns were wrong:
  * __import__(MODULE_NAME, globals(), locals(), MODULE_NAME)
    => Iterate through each character of MODULE_NAME as fromlist is expected to
       be a list/tuple.
  * __import__(MODULE_NAME, globals(), locals(), [MODULE_NAME])
    => This works but actually tries to import MODULE_NAME object from
       MODULE_NAME module (no error if it cannot).

The goal of such __import__ calls were for __import__ to return the right-end
module instead of the top-level package. In such case, `fromlist=['']` is the
way to go as it __import__ does not check if the object exists in the module if
it's an empty string. However, it is even better and easier to read to use
importlib.import_module() for that...

Also, add `from __future__ import absolute_import` because python2 tries both
relative and absolute import (level=-1 __import__ parameter) whereas python3
does absolute import by default (level=0).
