test(apiserver): add integration tests for P0+P1 backend features

Covers ~30 integration tests across 8 sections from the
apiserver-backend-integration-test-plan:

- §1: Cluster config push (store population, merge semantics, zero-preserve)
- §2: Host control (OnHostUpdated merge, validateHost, preCheck, batch ops)
- §3: Resource value push (all 7 value types, nil/unknown discriminant, overwrite)
- §4: Heartbeat keep-alive (interval update, zero-preserve)
- §5: Cross-feature (config+heartbeat, config+host, worker+config field preservation)
- §6: RBAC (cluster_admin bypass, algorithm confusion, expired tokens, hostgroup bypass)
- §7: Store thread safety (concurrent config pushes, host control+config, resource values)
- §8: Input safety (hostname length, empty lists, malformed payloads)

All tests use CGO_ENABLED=0 with //go:build !cgo build tag.
§8.1 hostname-length skipped pending P1-2b implementation.
