Add 59 Juniper OEM transceiver PIDs (SFP/SFP+/SFP28/QSFP+/QSFP28/ QSFP56/QSFP-DD/OSFP + DAC/AOC) to seed the transceivers table. Register scrape:catalog:juniper-oem in scheduler (daily 04:15). Fix BlueOptics scraper: force HTTP/1.1 via Node.js https.get() to bypass server bug where HTTP/2 returns empty response body. Also update catalog path from /transceivers/ to /Transceivers_1.
