feat(web): add khu-cong-nghiep, chuyen-nhuong, and reports pages

Add three new frontend page sections:
- Industrial parks (khu-cong-nghiep): listing, detail, filter bar
- Transfer listings (chuyen-nhuong): search, category tabs, detail
- AI reports dashboard: list, create, viewer with TOC

Includes components, API clients, hooks, server helpers, i18n keys,
navigation links in public and dashboard layouts, and lint fixes.
