Improve description of Suspend connection option

[NoRi2909]

When the suspend option in the user profile is enabled the browser connection is dropped after a tab or window remains in the background for five minutes. Bringing it back to the front will cause it to reconnect, meaning that the window content will take a while to refresh all entities shown.

The current wording is easy to misread, so a previous German translation turned this into "hiding the connection" which made no sense at all.

Proposed change

This PR changes the two strings to:

Suspend background connections
For hidden windows or background tabs close the server connection after 5 minutes.

This moves the main purpose into the headline, making it easier to further explain in the description below.

I agree that "suspend" is better than "close" as the connection is eventually restored
