Fix #5 category in search results, rename rooms chip (#6)

- #5: SearchSelect now shows the area/category as a muted right-aligned
  label on every dropdown item — visible at a glance whether a result is
  a Room, Kitchen, Garden etc. Typing the category name already filtered
  correctly; the label makes it clear without needing to read the group header.
  Applies to both the new-task location picker and the asset location picker.
- #6: Rename 'Rooms view' chip to 'Rooms Accessible View' to better convey
  that it shows which rooms staff can actually access right now.
