Purpose of this commit is to make ``get_access_action`` private as it is not
necessary to expose it directly. Website management is also made explicit
using a ``force_website`` parameter instead of relying on context key of the
same name. This allows to better understand the method code flow.
Contains also some code fix / improvements :
* Website forum: update code to better skip the frontend redirection if the
forum is not active and frontend is not forced;
* Website slides: respect force website parameter in redirection;
Task-2710804 (Mail: Clean Mail.Thread API)
Part-of: odoo/odoo#82167
As mail grows and will continue to grow, ordering views and having right
files is important to understand module organization and content.
Split main.py controller file into two files, one for mail related controllers
(redirections) and one for discuss.
Rename files according to guidelines for wizards and views.
No functional change comes with this commit. This is only code move.
