[CLAUDE] Backout: Chunk D — K5 cleanup F2 zombie endpoint + UsersPage column + DTO field

Reviewer K2 Major #1: PATCH /api/users/{id}/allow-skip-final endpoint Admin tick =
NoOp swallow silent (K1 sentinel → confusion UX). Full backout Plan D S22 stack:

BE drop (7 files):
- UsersController.cs: DELETE PATCH /allow-skip-final endpoint + SetAllowDrafterSkipToFinalBody record
- UserFeatures.cs: DELETE SetUserAllowDrafterSkipToFinalCommand + Handler
                    + UserDto.AllowDrafterSkipToFinal field
                    + list/get DTO mapping sentinel-false references
- ApprovalWorkflow.cs: REWRITE stale narrative line 78-80 (Reviewer Major #2 Mig 31 semantic)
                       + docstring AllowApproverSkipToFinal line 108 clean stale Users storage ref
- PurchaseEvaluationFeatures.cs: REWRITE Command DTO comment line 401 (Reviewer Minor #3)
- ApprovalWorkflowConfiguration.cs: APPEND Mig 31 narrative line 22-24 (Reviewer Minor #4)
                                     + clean storage move comment line 87
- ApprovalWorkflowV2AdminFeatures.cs: clean DTO comment line 58 stale "F2 xuống User table"
- IPurchaseEvaluationWorkflowService.cs + PurchaseEvaluationDtos.cs: clean stale
  "storage Users.AllowDrafterSkipToFinal" comments

FE Admin drop (2 files):
- UsersPage.tsx: DELETE "Skip cuối" column + FastForward badge + FastForward import
                  + allowSkipMut mutation hook + FastForward toggle button
- types/users.ts: DELETE allowDrafterSkipToFinal field

fe-user KHÔNG đụng (no UsersPage admin-only; K6 sẽ handle Workspace Drafter checkbox).
FE Designer page KHÔNG đụng (K3 done; 2 stale comment leftover deferred K6).

Plan K refactor F2 storage Users → Levels (Mig 31) complete cumulative cleanup.
Pattern reusable: post-refactor full cleanup (BE endpoint + Command + DTO + FE column
+ types + stale narratives) atomic 1 commit thay vì leak zombie state.

Verify:
- dotnet build production projects 0 err (2 pre-existing DocxRenderer warn)
- npm build fe-admin 0 TS err (no new warning)
- Grep AllowDrafterSkipToFinal + allow-skip-final + allowDrafterSkipToFinal zero results
  across src/Backend (excl Migrations history) + fe-admin/src
