fix(client/cordova/apple/macos): fix popover click and location issues (

#1845)

* chore(www): upgrade `server-list` to Lit

* Fix the "floating" location of the popover on initial load.

* Use the `NSPopover`'s native behavior to close the popover for us, instead of assuming responsibility for closing the popover in the app.
