fix(examples,tooling): migrate the one authored string sort fixture and re-key the moved doc-example ledger row

`examples/schema-catalog/src/schemas/plugin-view/object-view-list.json` authored
`table.sort: "name asc"` — the retired clause. `pnpm check` reported it by name
("did not validate as an ObjectUI schema"), and `objectui validate` gave the
reason: `table -> sort` expected array, received string. Migrated to
`[{ "field": "name", "order": "asc" }]`; the warning count moved 4 -> 3, which
is the firing control that the fixed file is the one that moved.

`scripts/check-doc-example-types.mjs`'s ledger is keyed by FILE:LINE, and the
`objectql.ts` edits shifted `ObjectFormSchema`'s example block 1604 -> 1607.
Re-keyed; `scripts/__tests__/check-doc-example-types.test.ts` is green again.
