feat(Contexts): add Contexts to navigation when applicable

[blizzz]

solves #863

needs #903 (soft)

wants nextcloud/server#44178

• generate correct link
• does not appear yet for the owner even if there is a share where display is enabled for all
• move logic from application to db query (see TODO remark in code)

Screenshot made with frontend from #844. On the content area in the UI we don't render the material icons yet, but the icon is in the nav bar. The icon over the mouse pointer is material design, while the two icons on the very right have fallback icons (default app icon).

Small comment otherwise looks straight forward

@enjeck what would be a nice addition is that the appropriate nav bar icon is set active, when being on an application that has an entry there (otherwise going back to tables).

I think this is tricky to do on the frontend. We may need a separate backend route to still render the TemplateResponse but then set the active entry on the navigation manager. We can then set an initial state that indicates that we're on an application page and to further adjustments on the frontend side like hiding the navigation by default. Something for a follow up I'd say.

Ah, I was speculating that such an option exist for fronted, but of course… why would it. There was no similar case before. Follow up is fine +1
