The concept of 'parent_id' on website.visitors was introduced in the saas-13.3
stable while implementing the "event online" feature:
However, it should have been part of the website module from the start since
it's a 'global' concept that does not depend on events at all.
See #53540 for more details.
This commit aims to clean the code by moving the field to the website module,
which allows a nice cleaning of associated overridden methods as well.
Along with that, we move the website.visitor demo data from the event module to
the website module, allowing a fresh install of website to showcase some of our
visitors feature.
We also took this opportunity to do some minor improvements in the visitors
kanban view in order to make relevant information more visible.
Task-2429652
Part-of: odoo/odoo#65113
PURPOSE
Clean organization and models linked to Event Online feature introduced in
semi stable saas-13.3 at odoo/odoo@981f95bbf4 and odoo/enterprise@14722028ae
Also clean website event menu not being available in website event but only
in website event track, which implies some extra-code to manage it.
In short: merge website_event_online in website_event, website_event_track
_(online/session) in website_event_track.
RATIONALE
_online modules have been added to extend content of website_event and
website_event_track without having any impact on those module. First step
of cleaning is to move this content directly in base module.
track_session module is mainly a rewrite of track module. Second step of
cleaning is to move its content directly in website_event_track.
SPECIFICATIONS
Move remaining content of website event online to website event.
Update dependencies accordingly.
