refactor(selection): replace concept sector filter with sub-industry

- pin the selection sector vocabulary to industry: the /sectors endpoint
  no longer accepts sector_type, and the port, adapter, and use case all
  resolve counts and member codes with sector_type="industry"
- relabel the results filter to 细分行业 and drop concept-type plumbing
  from the frontend API, query keys, and types
- show only 细分行业 in the signal detail panel; remove the concept-board
  chips and keep the snapshot-date tooltip on the industry line
- update backend and frontend tests to the industry vocabulary and record
  the revised scope in the task PRD
