feat: remove FM feature from Vector

FMs move to a separate application. Drops Fm/FmPart tables + Repair.fmId
column, deletes FM_OPENED/FM_CLOSED PartEvent rows, strips FM enums +
webhook events + shared contracts, removes FM routes/services/pages/UI,
and collapses dashboard admin ops to Repairs 7d/30d + trend + custody
backlog.
