Show calendar URIs alongside share icons.

[RokeJulianLockhart]

Is your feature request related to a problem? Please describe.

I frequently need to see a calendar's URI at a glance and/or compare it. Having to copy the link to my clipboard and into a text editor is mighty inconvenient.

Describe the solution you'd like

Show the URI of the calendar in its configuration pseudo-window.

Describe alternatives you've considered

What currently exists.

Additional context

https://github.com/Alinto/sogo has a great interface for this:

cc @jancborchardt @nimishavijay - with the new modal we should have some space for showing the URI, no?

Interesting suggestion! What info would the URI provide? Is it to just differentiate between different share links when there is more than one?

@nimishavijay, that indeed, and the myriad minor benefits gained, like being able to copy segments of the URI without having to first open a text editor.
