The signature-poll worker fetched every sent/partially_signed document via
GET /api/v2/envelope/{id}. Pre-cutover documents carry a bare numeric
documenso_id (e.g. "46"), which the v2 envelope endpoint rejects with 400
"Invalid envelope ID" — ~36 errors/hour on prod from 3 abandoned June-3 EOIs.
Skip documents whose documenso_id isn't an `envelope_xxx` string when the
port is on the v2 API (v1-API ports keep polling numeric ids). New v2 signing
is unaffected. Pure isPollableDocumensoId() helper, unit-tested.
