style: polish workspace UI — tab/pagination/table/nav-editor refinements

- Type tabs: gradient active state, pill counts, inset shadow container
- Pagination: bordered buttons with primary next, page info with accent
- Data table: hover highlight, uppercase headers, softer shadow
- Nav editor: proper 6-col grid alignment (handle/name/route/up/down/del),
  column headers row, focused input glow, red delete hover
