docs(spec): IApprovalService.recall names every actor who may recall, scoped by status (#15645)

The docstring said "Only the submitter (or a system context) may recall", then
widened to `returned` requests in a second paragraph. Both halves were wrong:

- The list was not exhaustive. A #3424 override actor (platform or tenant
  admin, holding no approver slot) may recall a `pending` request. The same
  file already documented that 387 lines above, where the docblock on
  `ApprovalRequestRow.viewer.can_override` spells the override's levers as
  `(approve / reject / reassign / recall it)`.
- The ADR-0044 widening read as if it applied to that whole list. It does not:
  the override and system arms are ANDed with `status === 'pending'` where they
  are computed, so neither reaches a `returned` request (#12775, maintainer
  ruling 2026-09-02). Abandoning a revision window is the submitter's alone.

Status is now the axis rather than a caveat appended to a general rule, so each
status carries its own admitted set. `ApprovalRecallInput.actorId` carried the
same stale sentence and is corrected with it. `ApprovalSendBackInput.actorId`
and `ApprovalResubmitInput.actorId` share the phrasing but are correct, since
`isOverrideActor` is never called from `sendBack` or `resubmit`.

Prose only: no key, no accepted value, no runtime behaviour moves.

+`IApprovalService.recall`'s contract prose names every actor who may recall, and scopes each one by status (#14670)
+
+**Documentation only — no key, no accepted value, no runtime behaviour moves.** The implementation has been correct since #12775; only the contract's description of it was stale.
+
+The docstring said *"Only the submitter (or a system context) may recall"*, then widened to `returned` requests in a second paragraph. Both halves were wrong, in opposite directions:
+
+- **The list was not exhaustive.** A #3424 override actor — a platform or tenant admin holding no approver slot — may recall a `pending` request. That is the in-product recovery path for an approval routed to an unstaffed position, and this same file already documented it 387 lines above the sentence denying it: the docblock on `ApprovalRequestRow.viewer.can_override` spells the override's levers as `(approve / reject / reassign / recall it)`. One file, two contradicting sentences about the same verb.
+- **The ADR-0044 widening read as though it applied to that whole list.** It does not. The override and system arms are ANDed with `status === 'pending'` where they are computed, so neither reaches a `returned` request; an override actor is refused there exactly as any other non-submitter (#12775, maintainer ruling 2026-09-02). Abandoning a revision window is the submitter's alone.
+
+The rewrite makes **status** the axis instead of appending a caveat, so the second defect cannot come back on a re-read: each status carries its own admitted set, and the `returned` bullet says outright that the submitter is alone in it.
+
+`ApprovalRecallInput.actorId` carried the same stale sentence (*"Must be the request's submitter (or a system context)"*) and is corrected with it. Fixing only the method docstring would have left the contradiction alive on the very input type the corrected method takes.
+
+The two sibling docstrings sharing that phrasing are **correct and unchanged**: `ApprovalSendBackInput.actorId` and `ApprovalResubmitInput.actorId`. `isOverrideActor` is called from exactly five places in `plugin-approvals` — `decideNode`, `reassign`, `recall`, `attachViewers` and `visibleRequestIds` — and neither `sendBack` nor `resubmit` is among them, so no override actor reaches either.
+
+The published prose already described the corrected rule (`content/docs/automation/approvals.mdx`: an admin "may act on any `pending` request — approve, reject, reassign it to a real approver, or recall it"). This docstring was the one surface that had not kept up.
