fix: improve empty state message when filters are active

When filters are applied but return no results, the empty state
now displays 'No documents found' without the request button or
'Choose the file to request signatures' text.

This provides better UX by distinguishing between:
- No documents in the system (shows request button)
- Filters with no matches (shows only message)
