anti 12e18b75db feat(swarm): expose needs_resync on TopologySummary + upsert record_error
Two small observability follow-ups to the phase-1 agent/topology wiring:

TopologySummary now carries needs_resync so operators can see the
heartbeat's resync flag via the topology list/detail API without
dropping into the DB.

TopologyStore.record_error becomes an upsert — when a docker/compose
failure fires during the first materialise (put() never reached), we
still land a marker row so GET /topology/state surfaces the error and
the next heartbeat carries an empty applied_version_hash. That empty
hash is what master's heartbeat check relies on to flag the topology
for resync instead of assuming the apply succeeded.

"""Phase 3 Step 1 — parity between repo dict output and Pydantic DTOs.
These tests pin the contract that repo-hydrated dicts deserialize
cleanly into the REST DTOs. If a repo-row shape drifts, the DTO test
fails before any endpoint rides on the stale contract.
