feat(extractors): expand catalog, smoke coverage, and sourcing docs

Adds Arc.dev, BC T-Net, Eluta, iCIMS tenants, QAJobsBoard, and SmartRecruiters

smoke-extractors and documents supplementary board access paths. Aligns Careerjet
v4 with the url query parameter and fixes strict typing in QAJobsBoard.
