feat: dashboard CRUD for Projects + Industrial Parks, listings delete, BĐS homepage card

Backend — DELETE endpoints (hard delete, ADMIN or owner):
- DELETE /projects/:id (Admin) — new DeleteProjectCommand/Handler,
  repository.delete() adapter, module wiring.
- DELETE /industrial/parks/:id (Admin) — same pattern.
- DELETE /listings/:id (JWT + owner-or-Admin check in handler).

Frontend — API clients:
- lib/du-an-api.ts: add create/update/delete + CreateProjectPayload,
  UpdateProjectPayload types.
- lib/khu-cong-nghiep-api.ts: add createPark/updatePark/deletePark +
  Create/Update payload types.
- lib/listings-api.ts: add delete().

Dashboard pages — new:
- /projects (Quản lý dự án): list with filters + edit/delete actions,
  /projects/new form (sectioned Cards, zod-validated), /projects/[id]/edit
  with danger-zone delete.
- /industrial-parks (Quản lý KCN): same triad. Fix occupancy-rate display
  (percentage already 0-100, no need to *100).

Dashboard listings page:
- Add Edit/Delete row actions with confirm + useMutation; error banner
  on mutation failure. Table view gains a "Thao tác" column; list view
  gains a footer action bar below each card.

Dashboard nav:
- Catalog group: /du-an → /projects (Quản lý dự án), /khu-cong-nghiep
  → /industrial-parks (Quản lý KCN). Desktop primaryNav updated too.

Public homepage:
- Add "Bất động sản" as a 5th feature card/tab → /search, using
  listingsApi for the "Featured listings" section.
- Bump grid to lg:grid-cols-5, update features subtitle copy ("Năm/Five
  core services").
