[FR] Hide response time on monitor widget

### Description

Have a property on the monitor widget to hide the response time for a more minimalist look.

Hide the `OK - 'x' ms` and have only the title showing, with properly centered line height. Then you'd still have the checkmark/error indicator to tell you the status of the service.

Start by locating the monitor widget implementation and the code that renders the response-time text. Add a configurable option to hide “OK - 'x' ms” while retaining the status indicator and centering the title. Done means the widget supports the minimalist display described in the issue without changing the default view.
