feat(plugin-approvals): expose per-group membership of pending approvers (objectui#2807)

per_group (会签) requests now carry pending_approver_groups on the enriched
row — each still-pending approver id mapped to the group key(s) it fills — so
a client can label each 'waiting on' chip with its group instead of showing
duplicate, context-free names.

- Resolved in attachDecisionProgress from the same open-time __approverGroups
  snapshot decision_progress already uses, so the two never disagree
- Only pending slots; synthetic (unnamed, #N) group keys dropped
- Absent for non-per_group behaviors; display-only
- Added to the ApprovalRequestRow contract in @objectstack/spec

Closes objectui#2807 (framework half)

+feat(plugin-approvals): expose per-group membership of pending approvers (objectui#2807)
+
+`per_group` (会签) requests now carry `pending_approver_groups` on the
+enriched row — a map from each still-pending approver id to the group key(s)
+it fills (e.g. `{ "u_devadmin": ["finance", "legal"] }`). A client can label
+each "waiting on" chip with the group it represents instead of showing
+duplicate, context-free names.
+
+- Resolved in `attachDecisionProgress` from the same open-time
+  `__approverGroups` snapshot the `decision_progress` groups already use, so
+  the two never disagree.
+- Only the **pending** slots are mapped (a resolved approver has left
+  `pending_approvers`), and **synthetic** (unnamed, `#N`) group keys are
+  dropped — a `· #0` sub-tag would be noise.
+- Absent for non-`per_group` behaviors. Display-only; the engine's
+  finalization tally stays authoritative.
+- Added to the `ApprovalRequestRow` contract in `@objectstack/spec`.
