fix(docker): query _prisma_migrations directly for failed-migration auto-resolve

The previous regex against `prisma migrate status` output silently drifted
out of sync with Prisma 6's wording, so today's failed migration on prod
was never auto-resolved — the container crash-looped and required a
manual DELETE on _prisma_migrations to recover.

Truth lives in the table: a row with `finished_at IS NULL AND
rolled_back_at IS NULL` is an unresolved failure. Query that directly via
the Prisma client (already shelled out for the user-count check below)
and loop until none remain (with a 5-iteration safety bound).
