e-pin the estate reusables to the last accepted standards ref (#57)

fix(ci): re-pin the estate reusables to the last accepted standards ref

Pins at `4e6ffe55`-or-later are rejected by GitHub's dependency-lockfile
validation, so the
callers that used them could not parse: `conclusion=failure`, **0
jobs**, run name equal to the
file's path. `210f14e7` (2026-09-12T17:32:17Z) is the last ref whose
pins are accepted — measured by
pinning a caller at each candidate and dispatching it, not inferred.

This re-points the refs here to that ref. Behaviour is otherwise
unchanged; the lockfile in
`hyperpolymath/standards` is the thing that has to be regenerated before
a forward re-point is safe
again, and the estate's own applier
(`.github/workflows/apply-workflow-pins.yml`) is what should do
that re-pointing once it can run.
