fix(suggest-path): resolve TypeScript build errors in CI

- Fix TS2352 in route handler: add intermediate `unknown` cast for
  SearchService to Record<string, unknown> type assertion
- Fix TS2322 in integration test: use ContentAnalysis type instead of
  typeof stockAnalysis so flow/stock variants are both accepted
