fix(seed): add required id to seed entries + make seed non-fatal

emdash seed validates that every content entry has an id (validate.ts),
but seed/seed.json entries only had slug — so seed aborted with 'id is
required' and, under set -e, crash-looped the pod (502). Set id=slug for
all 42 entries (conflict-detection keys off slug, so id is just the
seed-local ref key). Also move the seed step out from under set -e: a bad
content seed should log loudly but not take the whole site down (init
migrations stay fatal).
