chore(testserver): host networking, ports 8123/8124, smoke read+update, dbtrace pooled=0 verified

 - DONE P6: funcspec. `OnTxBegin`, `HookContext.SetTx`, `Handler.runInTx` for `SqlQuery` and `SqlQueryList`. `BeforeResponse` now runs in a second short tx (`Tx` is no longer the pool). `BeforeOp` is unchanged (still per statement). A begin/`OnTxBegin`/commit failure answers 500 `transaction_error` / "Transaction failed" (before, it returned with no response); body failures still answer via `sendError`. Tests: `pkg/funcspec/tx_test.go`.
 - DONE (AfterRead, decided by user): restheadspec `AfterRead` now runs in a second short tx. Test: `pkg/restheadspec/read_tx_test.go`.
 - DONE P7: `pkg/security/txsettings.go`: `SecurityList.SetTxSettings(fn)`, `StampTxSettings`, `ApplyTxSettings` (configurable map, decided by user; `set_config(name, value, true)`, value hex-encoded, name validated, Postgres only, fail closed). Every spec's `RegisterSecurityHooks` registers it on `OnTxBegin`. Tests: `pkg/security/txsettings_test.go`, `pkg/resolvespec/tx_settings_test.go`. Docs: `pkg/common/TRANSACTIONS.md`.
-- NEXT: extra tests (create/update for other specs, `dbtrace` `pooled == 0` on real Postgres).
+- DONE real-Postgres check (resolvespec, testserver via compose): create `tx=1 pooled=0`, read `tx=1 pooled=0`, update `tx=2 pooled=0` (was `pooled=1`), single delete `tx=1 pooled=0`, batch create/delete `tx=1 pooled=0`. Compose now uses host networking (bridge fails here): testserver on 8123, Postgres on 8124 (was 8080/5434); integration test DSNs updated. Smoke script covers read and update. websocketspec/mqttspec/resolvemcp/restheadspec/funcspec not measured on real Postgres.
+- NEXT: extra per-spec create/update tests (optional).
 
 ## Tests
 - Existing: per-spec `handler_test.go`, `hooks_test.go`, `integration_test.go`; models in `pkg/testmodels/business.go`; `dbtrace` unit tests.
