[Feature Request] Editing default view settings for Guest user

[Archinowsk]

I'm using calibre-web to host a public roleplaying library page (roolipelikirjasto.fi). I would like to edit Guest user default view settings. Specifically, I would like the Series page to default into using List instead of Grid.

Seems the Guest user view_settings are only loaded from flask_session (ie cookie):

calibre-web/cps/ub.py

Lines 329 to 330 in efc7ce3

	def get_view_property(self, page, prop):
	if 'view' in flask_session:

view_settings from DB seem to also be available:

calibre-web/cps/ub.py

Line 311 in efc7ce3

self.view_settings = data.view_settings

For Guest user, would it be possible to get view_settings using DB user.view_settings if flask_session is missing?

def get_view_property(self, page, prop):
    if 'view' in flask_session:
        if not flask_session['view'].get(page):
            return None
        return flask_session['view'][page].get(prop)
+   if self.view_settings.get(page):
+      return self.view_settings[page].get(prop)
    return None

In this case, I would be editing user.view_settings directly to DB. I understand this is somewhat niche feature request 😅.
