Clarify ProvidersStep sort button + bold results count

- Sort button now reads "Sort: <value>" so it's distinguishable from
  a filter; aria-label spells out the current sort. Price sort labels
  dropped their internal colons (avoids double-colon rendering).
- Results count bolds the number in primary text so it registers as
  the subject rather than incidental metadata.
