Add cursor-based pagination to /analyze/batch and /jobs endpoints

- Fix route ordering bug: GET /analyze/batch was shadowed by
  GET /analyze/{company_name} causing all GET requests to /analyze/batch
  to be erroneously handled as single-company analysis (503). Move
  /analyze/batch GET registration to before the {company_name} route.
- Update TypeScript schema.d.ts: add AnalysisRecord, PaginatedAnalysisResponse,
  PaginatedJobsResponse schemas; add GET /analyze/batch operation with
  cursor+limit+company_name params; update list_jobs_jobs_get to include
  cursor param and return PaginatedJobsResponse.
- Update frontend/src/api/client.ts: add listBatchAnalyses() method with
  cursor/limit support; update listJobs() to accept cursor and return
  PaginatedJobsResponse; default limit changed from 10 to 50.
- Update frontend/src/types/index.ts: export AnalysisRecord,
  PaginatedAnalysisResponse, PaginatedJobsResponse.
- Expand tests/test_pagination.py: add auth fixture so tests pass JWT
  validation; add 11 new /jobs tests covering first page, last page,
  subsequent pages, empty results, status filter, limit boundaries, cursor
  forwarding, and paginated response shape.
