Add Comms-Express, Router-Switch.com, Multimode Inc, OpticTransceiver.com, and Wiitek scrapers covering CFP2-DCO, CFP4, OSFP224, QSFP112, CXP, GBIC, XENPAK, CSFP, SFP-DD, SFP56, QSFP56 and other previously-uncovered form factors. Each scheduled every 8h. Worker registrations added to scheduler. Also export db alias in utils/db.ts to fix eBay enricher + community scrapers crashing with 'Cannot read properties of undefined (reading query)'.
