[CLAUDE] App+Api+Docs: Chunk E1 — List endpoint + Bypass-review + Notify TPB + chốt session 8

3 endpoint mới + Notify TPB + Docs update để chốt session 8.

Application:
- PurchaseEvaluationDepartmentApprovalFeatures.cs (NEW):
  * ListPeDepartmentApprovalsQuery + DTO PeDepartmentApprovalDto
  * Join Departments (lấy Name) + lookup Users.FullName denorm cho FE timeline
- UserFeatures.cs: SetUserBypassReviewCommand + Handler dùng UserManager.UpdateAsync
- IApplicationDbContext: thêm DbSet<User> Users + DbSet<Role> Roles (cần cho lookup)

Api:
- PurchaseEvaluationsController: GET /api/purchase-evaluations/{id}/department-approvals
- UsersController: PATCH /api/users/{id}/bypass-review (Authorize Users.Update)

Infra:
- PurchaseEvaluationWorkflowService: notify TPB cùng dept khi NV review.
  Query db.Users.Where(DeptId match + IsActive) → UserManager.GetRolesAsync
  filter DeptManager → notifications.NotifyAsync. Best effort fail non-critical.

Docs:
- STATUS.md: Recently Done thêm row session 8 + Phase header update
  count 52→55 tables, 15→16 migrations, 128→131 endpoints
- HANDOFF.md: TL;DR session 8 + 8 cảnh báo session 9 (FE chưa làm,
  test flow anh Kiệt, smart reject test, lock edit test, ...)
- migration-todos.md: Phase 9 done section đầy đủ 3 ràng buộc + pending Chunk E-bis
- CLAUDE.md: count 52→55 + migration 16 description
- session log: 2026-05-04-1230-chot-session-8-2-stage-dept-approval.md (full report)

Verify final:
- Build pass 0 warning 0 error
- 77 unit test pass (54 Domain + 23 Infra)
- Migration 16 applied LocalDB OK + schema verified

Total session 8 cumulative: 5 commit per-chunk:
- 5fe61cc (A: Migration 16 schema)
- 14f3c9f (B: Lock edit guards 17 handler)
- 9747f8c (C: Smart reject + Resume 3 module)
- a532ba6 (D: PE 2-stage logic)
- (current E1: List + Notify + Bypass + Docs)

- FE UserManager toggle CanBypassReview
- HĐ + Budget 2-stage extension
- Tests Phase 3 mini cho 2-stage Service-layer logic
