[CLAUDE] FE: accordion mutex Pe_* + sidebar width w-72 + label nowrap

2 fix user session 3:

1. Accordion mutex cho Pe_ groups (2 phieu Duyet NCC + Duyet NCC va
   Giai phap) — truoc chi Ct_ (7 HD) co mutex, Pe_ dung localOpen rieng
   → user click 1 Pe_ group xong click Pe_ khac → ca 2 expanded cung luc.
   Fix: extend AccordionContextValue + expandedPeCode + INT_TO_PE_CODE
   map. MenuGroup branch: isCtAccordion || isPeAccordion (families doc
   lap — user co the mo 1 Ct_ + 1 Pe_ cung luc). useEffect URL sync:
   /purchase-evaluations?type → Pe; /contracts* ?type → Ct.

2. Sidebar width w-64 (256px) → w-72 (288px) de label QUY TRINH CHON
   THAU PHU - NCC (30 char uppercase tracking-wide) fit single-line
   thay vi wrap 2 dong. Top-level group class:
     text-xs tracking-wider → text-[11px] tracking-wide + whitespace-nowrap
   Dong bo ca fe-admin + fe-user.
