After [1], the frontend 'page properties' dialog was replaced by a 'form
view dialog' of the current 'website.page'.
The dialog structure in [1] was based on a 'PagePropertiesDialogWrapper'
component that handles a 'legacy formViewDialog' widget of the page.
Since 'FormViewDialog' is available as OWL component (starting from [2]),
we can now simplify the current code from:
A- 'PagePropertiesDialogWrapper': creates & opens a legacy FormViewDialog.
to:
B- 'PagePropertiesDialog' (the page formViewDialog): can simply be added
using 'dialog service'.
Remark: a wrapper ('PagePropertiesDialogManager' component) is used
temporarily by the legacy 'website.page' listView to add
'PagePropertiesDialog','DuplicatePageDialog' & 'DeletePageDialog'.
This component should be removed after the update of the listView to OWL
and components will be added using 'dialog service' as in the website
navbar menu code.
Follows the merge of the 'website in backend' task at [1].
