Traces: Fixed missing CopyButton on KeyValueTables and overlapping of panels (#49271)

* rewrote `CopyIcon` to an functional component

- fixed missing `CopyIcon` on `KeyValuesTable`

* added fixed height of `30px` to `KeyValuesTable` to fix overlapping

* removed unused CopyIcon snapshot

* KeyValuesTable: moved `30px` height from `tr` to `td` to fix vertical alignment
