Add: Web UI (React 19 + Vite + shadcn/ui) + FastAPI REST layer

Adds a self-contained web interface that wraps the MCP tools so end users
don't need to issue MCP commands. Single Docker container serves:

  /              → React SPA (RTL Hebrew, Heebo font, shadcn/ui components)
  /api/*         → FastAPI REST endpoints used by the SPA
  /api/docs      → OpenAPI / Swagger
  /mcp           → existing FastMCP streamable-http endpoint
  /health        → liveness probe

REST endpoints (in nadlan_mcp/web_app.py):
  GET  /api/search/address?q=...  — autocomplete + best-effort gush/חלקה
                                    via Govmap PARCEL_ALL layer
  POST /api/search/deals          — Govmap deals around an address
  POST /api/search/appraisals     — Decisive-appraiser search (gov.il)
  GET  /api/appraisals/pdf?url=.. — Stream PDFs through this server,
                                    carrying the upstream x-client-id
                                    header (a normal browser fetch fails)

UI flow:
  - Address search → resolves gush/חלקה → shows BOTH deals (Govmap) AND
    appraiser decisions (gov.il) for the same parcel side-by-side in tabs.
  - Block+plot search → goes straight to appraisals.
  - Appraiser-name search → all decisions by that appraiser.

Stack chosen for RTL-first usability and longevity: React 19, Vite 6,
TypeScript, Tailwind, shadcn/ui (Radix primitives), TanStack Query,
Lucide icons. ~295KB gzipped JS, no SSR overhead.

Multi-stage Dockerfile: Node 22 builds web/ in stage 1, Python 3.13
runtime serves the dist + the FastAPI app in stage 2.
