feat(ancpi): complete ePay UI + dedup protection

UI Components (Phase 4):
- epay-connect.tsx: connection widget with credit badge, auto-connect
- epay-order-button.tsx: per-parcel "Extras CF" button with status
- epay-tab.tsx: full "Extrase CF" tab with orders table, filters,
  download/refresh actions, new order form
- Minimal changes to parcel-sync-module.tsx: 5th tab + button on
  search results + ePay connect widget

Dedup Protection:
- epay-queue.ts: batch-level dedup (60s window, canonical key from
  sorted cadastral numbers)
- order/route.ts: request nonce idempotency (60s cache)
- test/route.ts: refresh protection (30s cache)
