feat: load ahdcAdcGains table in ALERTEngine

mathieuouillon · mathieuouillon · commit 3f33269e9deb · 2026-04-10T10:01:41.000-04:00
Register /calibration/alert/ahdc/gains in ALERTEngine's init() and refresh the IndexedTable reference on run change, so it is available for downstream use. Requested by @ftouchte for an upcoming pull request.
