fix: move group tag into category cell and hide on mobile

- Relocate group tag from expand row to category column so it appears inline beside the category tag
- Add margin between stacked tags with .col-cat .tag + .tag spacing rule
- Remove fixed width from .col-cat; narrow .col-name from 35% to 30% to give category column room
- Hide .tag-group on screens ≤900px and widen .col-name to 50% to reclaim space
