fix: address CTO review feedback on quick-find search (GH #97, GRO-134)

- Remove unused makeSelectChain function from search.test.ts (lint blocker)
- Fix handleClientClick/handlePetClick to navigate to /admin/clients?highlight={id}
  so the target client is identified in the URL rather than silently ignored
- Add console.warn for fetch errors in GlobalSearch instead of swallowing silently

Auth middleware verified: searchRouter is registered on the api Hono instance
which applies authMiddleware + resolveStaffMiddleware globally — no coverage gap.
