💄 Fix small styling bugs on redaction page

- The page number element in the pagination button group had rounded corners
- The fa-icons on the confirm redaction button & no redaction were too close to the text and needed a bit of margin
- The sub-btn-group in the manage attachments page was not shown as part of the btn-group (i.e. had rounded corners)
