chore(dev): bump iceberg-rest-fixture to 1.11.0

The local REST catalog used by the integration tests (`dev/docker-compose.yaml`)
was pinned to `apache/iceberg-rest-fixture:1.10.0`, which only ships the
scan-planning wire types — it has no server-side planning handler and does not
advertise the scan-plan endpoints in `GET /v1/config`.

`1.11.0` adds the server-side implementation: `CatalogHandlers.planTableScan`/
`fetchScanTasks`, the adapter routes (`PLAN_TABLE_SCAN`/`FETCH_PLANNING_RESULT`/
`FETCH_SCAN_TASKS`/`CANCEL_PLAN_TABLE_SCAN`), and advertises them via
`Route.values()` in the config response. Bumping lets the integration tests
exercise server-side features (e.g. scan planning, #1690) against the local
fixture.
