* ci: run migrations against Postgres service container in CI
Add a migrate job that applies node-pg-migrate against an ephemeral
Postgres 16 service container so broken migrations fail at PR time.

* fix(migrations): retimestamp scan tables after initial-schema.
Fresh CI/postgres runs failed because 1748365200000 sorted before
initial-schema. Renamed to 1779853647566 with IF NOT EXISTS guards intact.

* fix(migrations): ensure is_system_collection exists before description backfill.
Fresh CI Postgres runs initial-schema without this column (added historically
via scripts); ADD COLUMN IF NOT EXISTS makes the data migration safe on new
and existing envs.

Existing is_system_collection rows may carry stale copy; align them with VOCAB.SYSTEM_COLLECTION_SEED_DESCRIPTION so UI matches new signups.
