feat: add version display on login page and sidebar (v1.4.0)

- Login page: shows "vX.Y.Z | Core: vA.B.C" at bottom of card
- Sidebar footer: shows version when expanded
- Calls GET /api/v1/version (no auth required)
- For field engineers to instantly identify platform version

 # EMS Frontend Template
 
-Base React frontend template for EMS customer projects.
+> Base React/TypeScript UI template for EMS customer projects
 
-## Usage
+**Current Version: 1.2.0** | See `VERSIONS.json`
 
-When creating a new customer project, copy this template:
+This is the shared frontend template used to bootstrap new EMS customer frontends. Copy it into a new customer repo and customize.
+
+---
+
+## Usage — New Customer Setup
 
 ```bash
+# Copy template into customer repo
 cp -r ems-frontend-template/ <customer-repo>/frontend/
 cd <customer-repo>/frontend
+
+# Install dependencies
 npm install
+
+# Start dev server
+npm run dev
+# Opens at http://localhost:3000, proxies /api to localhost:8000
 ```
 
-Then customize:
-1. Edit `src/App.tsx` — add/remove routes per customer needs
-2. Edit `src/layouts/MainLayout.tsx` — customer branding (logo, colors, sidebar)
-3. Edit `package.json` — remove unused deps (e.g., Three.js if no 3D)
-4. Edit `vite.config.ts` — update proxy target if backend port differs
+### Customize for your customer:
+
+1. `src/contexts/ThemeContext.tsx` -- Branding colors, customer name
+2. `src/layouts/MainLayout.tsx` -- Logo, sidebar menu items
+3. `src/App.tsx` -- Add/remove routes per customer needs
+4. `vite.config.ts` -- Update proxy target if backend port differs
+5. `package.json` -- Remove unused deps (e.g., Three.js if no 3D)
+6. Update `VERSIONS.json` -- Set new project name and version
