test(lint): restore the ObjectForm half of the parse-gate mixed-spelling fixture

The `parseable` array in `validate-react-page-props.test.ts` is the
FALSE-POSITIVE CONTROL for the syntax gate: every entry asserts only
`not.toContain(REACT_PAGE_SOURCE_UNPARSEABLE)`, so it grades the PARSE and
nothing else. One entry carries an `ObjectForm` and a `ListView` in a single
fragment. Retiring the `ListView` binding aliases re-spelled BOTH halves to
`data={{ provider: "object", object: "a" }}`, but only the `ListView` half is
in that retirement's scope: `ObjectForm` binds by its own props and carries the
shared `OBJECT_NAME` overlay (`packages/spec/src/ui/react-blocks.ts`, the
`REACT_BLOCKS` entry for `ObjectForm`), which is `objectName`, required. It has
no `data` prop at all — neither in its `interactions` nor in its `dataProps`.

The fixture therefore spelled a prop the contract does not carry. Because the
array grades parseability only, both spellings parse and CI stayed green: no
gate in the repo could see it.

Restore the `ObjectForm` half to `objectName="a"` and keep the `ListView` half
canonical, which is what the entry was — a genuine MIXED-SPELLING fragment, and
a stronger parse fixture than either uniform spelling.

Measured over whole file text (never line-oriented, so a hard-wrapped
occurrence cannot hide), across the full diff versus the merge base: the
`objectName=` prop sites attributed to `ObjectForm` are 16 -> 16 and to
`ObjectChart` 36 -> 36 — both unchanged — and `ListView` is the only tag that
gains the canonical `data` spelling.
