Pasting a zulip URL in the search bar should go there

[nomeata]

Problem Description

I use the zulip destop app. Sometimes I receive zulip links (email, direct message, or on zulip in a different org). Clicking on the link opens the browser, which is not where I want to interact with zulip.

Proposed Solution

Something natural to try is to take the link and paste it in the Desktop app’s search bar. Right now this does not lead to anything useful, but it could recognize the link and jump directly to it, as if I clicked on it in a message within the app.

Describe alternatives you've considered

This would be less needed if opening a zulip link on the browser would offer me to then open it in the app instead (like for example WhatsApp does).

Also, at least for the use case of inter-org zulip links, fixing #1219 would address this usecase for me in some cases.
