[CLAUDE] FE-Admin+FE-User: PurchaseEvaluation pages (3-panel list + tabs detail)

Types + pages + components cho module Duyệt NCC ở cả 2 FE (copy-share).

Pages:
 - PurchaseEvaluationsListPage: 3-panel lg:grid-cols-[340px_1fr_360px]
   * Panel 1: list filter theo type/phase/search + pendingMe inbox mode
   * Panel 2: PeDetailTabs (Thông tin/NCC/Hạng mục/Duyệt/Lịch sử)
   * Panel 3: PeWorkflowPanel với timeline + nextPhase buttons
   * Mobile fallback fullpage /purchase-evaluations/:id
 - PurchaseEvaluationCreatePage: form create/edit header (Type / Tên gói thầu
   / Dự án / Địa điểm / Mô tả / PaymentTerms JSON). Suppliers+Details+Quotes
   thêm sau khi save ở Detail tabs.

Components:
 - PeDetailTabs: 5 tab + dialogs (AddSupplier/EditSupplier/DetailDialog/
   QuoteDialog) + matrix N NCC × M hạng mục clickable cells + select winner
 - PeWorkflowPanel: policy timeline từ BE workflow.activePhases + transition
   confirmation dialog với comment

Routes (cả 2 app):
 - /purchase-evaluations (+ ?type=1|2&pendingMe=1&id=...)
 - /purchase-evaluations/new (+ ?type / ?id để edit)
 - /purchase-evaluations/:id (mobile fullpage)

Menu resolver:
 - Pe_<Code>_List → /purchase-evaluations?type=N
 - Pe_<Code>_Create → /purchase-evaluations/new?type=N
 - Pe_<Code>_Pending → /purchase-evaluations?type=N&pendingMe=1
 - PeWf_<Code> (fe-admin only) → /system/pe-workflows/<code>

Skip MVP: PE Workflow admin designer UI, PE Attachments. TS build pass
cả 2 app.
