[CLAUDE] FE-Admin FE-User: Chunk L2 — Fix F4 BudgetAdjustSection bypass readOnly khi Approver scope (menu Duyệt)

Bro UAT S23 t2 catch: "Đã stick cho edit trong luồng duyệt nhưng trong menu
duyệt -> vẫn không edit đc ngân sách". Investigator audit root cause:
- BudgetAdjustSection canAdjust = !readOnly && (...) — `!readOnly` short-circuit
  block F4 logic
- Menu Duyệt route truyền readOnly=true xuống PeDetailTabs → button "Điều chỉnh"
  hidden dù admin đã tick AllowApproverEditBudget cho slot + actor match
- F3 wire ItemsTab ĐÚNG via `itemsReadOnly = readOnly && !approverEditMode`
  pattern bypass — F4 không follow same pattern

Refactor canAdjust × 2 app (rule §3.9 mirror):
```
- canAdjust = !readOnly && (isAdmin || (isDrafter && isDrafterPhase) || isApproverChoDuyet)
+ canAdjust = isAdmin
+   || (!readOnly && isDrafter && isDrafterPhase)
+   || isApproverChoDuyet
```

→ F4 Approver scope (Mig 30) BYPASS readOnly:
- Admin: bypass readOnly (full quyền)
- Drafter (Nháp/TraLai): chỉ Workspace (readOnly=false)
- Approver ChoDuyet + flag tick + actor match: bypass readOnly → button "Điều chỉnh"
  visible trong menu Duyệt

Mirror F3 pattern (itemsReadOnly line 118). F4 wire S22+5 ban đầu miss BYPASS
pattern — fixed S23 t2.

Verify:
- npm run build × 2 app pass (0 TS err, bundle hash rotated)
- Bro UAT verify: tick F4 → vào menu Duyệt → click "Điều chỉnh ngân sách"
  → modal open editable

Pattern lesson saved memory: per-NV admin opt-in flag wire RULE — FE bypass
readOnly khi flag tick + actor match + phase match (mirror F3 itemsReadOnly).
F4 BudgetAdjustSection retroactive fix.
