  1. 'Solve Divergences' action:
     => Display Delivery_viewSolveDivergenceDialog.listbox:
        -> Delivery_getSolverDecisionList
           -> Delivery_getSolverProcess => create Solver Process in 'draft' state and build Solver Decisions.
  2. Clicking 'Update' button updates Solver Decisions.
  3. Click 'Solve Divergences' button after either 'Adopt Prevision' or 'Accept Decision'.
     => SolverProcess.solve():
        Solver Process transit to 'solving' state and 'solve' Activity is created.

Before this Activity is executed, user can still select 'Solve Divergences'
action and this will create another 'Solver Process' as the current one is not
in 'draft' state anymore. Moreover, another user can still 'Adopt Prevision'
(while the first user selected 'Accept Decision') and this will be actually be
applied despite the first user choice.

Instead, create Solver Process when transiting to 'diverged' state and do not
display 'Solve Divergences' button nor allow access to 'Solve Divergences
Dialog' (Delivery_viewSolveDivergenceDialog) if there is a Solver Process in
'solving' state.

erp5_simulation: Display Divergence dialog even if there is nothing to solve (same as legacy Simulation Dialog).

This fixes the following Site Error when there is no Divergence to solve:
  AttributeError: 'NoneType' object has no attribute 'SolverProcess_getSolverDecisionList'

This may happen if user selects 'Solve Divergence' Action and solve
Divergences, then immediately goes back and selects again this action
whereas there is actually no Divergence to solve.

erp5_officejs_support_request_ui: Initial implementation for an application which let user can create custom support request

This commit includes:
erp5_officejs_support_request_ui: The implementation itself.
erp5_officejs_support_request_ui_test: The test of it.

OTherwise, the value is rounded during the division, and the call to ceil becomes useless

In nexedi/erp5!225 we realized google gadgets ( calendar, clock, maps and search ) no longer work since years, since they were hosted on google servers and they are longer hosted there.

Gadget framework is still working, our own gadgets (persons, worklists etc) too, in this merge request we just remove the gadgets that were hosted on google and not longer work.

I believe they were kind of example and we should not reimplement them or try to replace them.

For years, erp5_calendar was keeping a duplicated copy of [`z_catalog_stock_list`](https://lab.nexedi.com/nexedi/erp5/blob/985bbc0f716397c899e6af69ef431db86923ab34/product/ERP5/bootstrap/erp5_mysql_innodb_catalog/CatalogMethodTemplateItem/portal_catalog/erp5_mysql_innodb/z_catalog_stock_list.sql). In a79ca4c1, the functionality was merged in erp5_mysql_innodb and the duplicated copy was removed from erp5_calendar.

Problem is that when we update erp5_calendar, `z_catalog_stock_list` is removed.

We discussed in nexedi/erp5@a79ca4c1 (comment 15577) and suggested to use *Path of objects that should be kept* like we already did in some other business templates.

I tried, but it did not work, because [`CatalogMethod.preinstall`](https://lab.nexedi.com/nexedi/erp5/blob/985bbc0f716397c899e6af69ef431db86923ab34/product/ERP5/Document/BusinessTemplate.py#L2995)  overwrites the returned value of [`ObjectTemplateItem.preinstall`](https://lab.nexedi.com/nexedi/erp5/blob/985bbc0f716397c899e6af69ef431db86923ab34/product/ERP5/Document/BusinessTemplate.py#L1117)  (which supports template_keep_path_list) with the returned value of [`BaseTemplateItem.preinstall`](https://lab.nexedi.com/nexedi/erp5/blob/985bbc0f716397c899e6af69ef431db86923ab34/product/ERP5/Document/BusinessTemplate.py#L485) which does not support it.

My understanding is that the former is necessary to install the z sql methods and later to install the configuration on the catalog
 ( see efe5294e ), but the order does not really mater, so it's safe to give priority to `ObjectTemplateItem.preinstall`.

I also add some tests for template_keep_path_list, I think it was not tested, and modified erp5_calendar as suggested.

Payroll related document classes (AnnotationLine,  PaySheetLine, PaySheetTransactionLine, PaySheetCell) are not different from Invoice-related classes.

This work aims to remove these document classes and base the portal types on the generic invoice classes.

This work started after finding out that Pay Sheet Lines were appearing in the "Account Statement" report, on side of Pay Sheet Transaction Lines. This happened as PaySheetLines is overiding the "isAccountable" method to return True. This merge request, besides removing duplicate code, fixes the accountable property of Pay Sheet Lines, and updates the call to the inventory API to generate correct accounting/payroll reports.
