fix: resolve 404 errors and API routing issues

Backend Fixes:
- Fixed Dockerfile: Changed from PHP/Apache to Node.js (required for API)
- Fixed server.js: Moved API routes BEFORE static files (prevents 404 on API calls)
- Fixed static file serving: Now serves from current directory

Frontend Fixes:
- Fixed UIManager: Made all methods static to match usage pattern
- Added HTML escaping to prevent XSS in notifications and UI display
- Fixed chat.js: Removed instance UIManager reference
- Fixed scanner.js: Removed instance UIManager reference, added escaping
- Fixed project.js: Added HTML escaping for file names
- Fixed app.js: Graceful error handling for initial load

Issues Resolved:
- POST /api/chat/start returns 404 Fixed routing order
- POST /api/chat/message returns 404 Fixed routing order
- 'SyntaxError: Unexpected token' Fixed by serving API, not HTML
- 'showError is not a function' Fixed UIManager static methods

New Features:
- Added start.sh for Unix/Linux startup with env var defaults
- Added start.cmd for Windows startup with env var defaults
- Better error messages and graceful degradation

The server now correctly:
- Routes API requests to Express handlers
- Serves HTML/CSS/JS as static files
- Handles missing project data without crashing
- Shows proper error messages to users

-
-## Local Development
-
-### Prerequisites
-
-- Docker and Docker Compose (or Docker Desktop)
-- Git
-- Code editor (VS Code recommended)
-
-### Run Locally
-
-```bash
-# Clone the repository
-git clone https://github.com/NLarchive/my-webapp-hf.git
-cd my-webapp-hf
-
-# Build the Docker image
-docker build -t my-webapp .
-
-# Run the container
-docker run --rm -p 7860:7860 my-webapp
-```
-
-**Access the app**: http://localhost:7860
-
-### Making Changes
-
-1. Edit files in the `public/` folder
-2. Save files
-3. Refresh your browser (no restart needed for static/PHP files)
-
-**For Docker changes** (if modifying `Dockerfile`):
-```bash
-docker build -t my-webapp .
-docker run --rm -p 7860:7860 my-webapp
-```
-
----
-
-## Deployment
-
-### Option A: Automatic (Recommended)
-
-Every push to `main` on GitHub triggers auto-sync to Hugging Face:
-
-```bash
-git add .
-git commit -m "Your changes"
-git push origin main
-# ✅ GitHub Action automatically syncs to HF Spaces
-```
-
-### Option B: Manual Push
-
-```bash
-git remote add hf https://huggingface.co/spaces/NLarchive/my-webapp-hf
-git push --force hf main
-# Username: NLarchive
-# Password: Your HF Token
-```
-
-### First-Time Setup
-
-1. Create HF Space at https://huggingface.co/spaces
-2. Set SDK to **Docker**
-3. Get HF token: https://huggingface.co/settings/tokens
-4. Add to GitHub secrets: `Settings` → `Secrets and variables` → `Actions` → `New secret` (name: `HF_TOKEN`)
-
----
-
-## GitHub Actions Workflow
-
-**File**: `.github/workflows/sync-to-hf.yml`
-
-**Triggers**: Every push to `main` branch
-
-**Steps**:
-1. Checkout code (with LFS support)
-2. Check for files >10MB (prevents LFS issues)
-3. Configure git user
-4. Push to Hugging Face Space with force update
-
-**Status**: Check at https://github.com/NLarchive/my-webapp-hf/actions
-
----
-
-## API Endpoints
-
-### `GET /api.php`
-
-Returns server status and metadata.
-
-**Response**:
-```json
-{
-  "message": "PHP is working correctly! ✓",
-  "timestamp": "2025-11-17 20:30:00",
-  "random": 742,
-  "php_version": "8.2.x",
-  "server": "Apache/2.4.x (Ubuntu)"
-}
-```
-
-### `POST /process.php`
-
-Processes form data and returns greeting.
-
-**Parameters**: `name` (string)
-
-**Response**:
-```json
-{
-  "success": true,
-  "greeting": "Hello, Sam! Your form was processed by PHP.",
-  "timestamp": "2025-11-17 20:30:05",
-  "name_length": 3
-}
-```
-
----
-
-## Troubleshooting
-
-### GitHub Actions Fails
-
-**Issue**: Workflow shows failure  
-**Solution**: Check GitHub Actions logs at https://github.com/NLarchive/my-webapp-hf/actions
-
-Common causes:
-- `HF_TOKEN` secret not set (add it to GitHub repo settings)
-- Invalid YAML in README front matter (use only `indigo`, `yellow`, `red`, etc.)
-
-### Docker Build Fails Locally
-
-**Issue**: `docker build` returns error  
-**Solution**: Ensure Dockerfile syntax is correct:
-```bash
-docker build --no-cache -t my-webapp .
-```
-
-### HF Space Shows 502
-
-**Issue**: "Bad Gateway" error on HF  
-**Solution**: 
-1. Check build logs at your Space's "Build logs" tab
-2. Wait 2–5 minutes (first build takes time)
-3. Verify `Dockerfile` is at repo root and `public/` is correctly copied
-
-### PHP Functions Not Found
-
-**Issue**: "Call to undefined function" error  
-**Solution**: Verify PHP extension is installed. Check Dockerfile comment for optional extensions.
-
-### Colors Invalid in README
-
-**Issue**: Push rejected: "colorFrom must be one of..."  
-**Solution**: Use only these values: `red`, `yellow`, `green`, `blue`, `indigo`, `purple`, `pink`, `gray`
-
----
-
-## Adding New Features
-
-### Add a New HTML Page
-
-1. Create `public/new-page.html`
-2. Link from `index.html`: `<a href="new-page.html">New Page</a>`
-3. Push to GitHub (auto-syncs)
-
-### Add a New API Endpoint
-
-1. Create `public/custom-api.php`:
-   ```php
-   <?php
-   header('Content-Type: application/json');
-   echo json_encode(['data' => 'your response']);
-   ?>
-   ```
-2. Call from `script.js`:
-   ```js
-   fetch('custom-api.php')
-     .then(r => r.json())
-     .then(data => console.log(data));
-   ```
-3. Commit and push
-
-### Modify Styling
-
-1. Edit `public/styles.css`
-2. Refresh browser (no rebuild needed)
-
-### Update Dockerfile
-
-1. Edit `Dockerfile` (e.g., install packages, add extensions)
-2. Test locally: `docker build -t my-webapp .`
-3. Commit and push (auto-rebuilds on HF)

-
-## Performance Tips
-
-- **Minify CSS/JS** for production (currently human-readable)
-- **Cache Control**: Add headers for static assets in Apache config
-- **Compress**: Enable gzip in Apache for faster loads
-- **CDN**: Use a CDN for large assets (images, fonts)
-
----
-
-## Security Notes
-
-- ✅ Form inputs sanitized with `htmlspecialchars()`
-- ✅ CORS headers set (`Access-Control-Allow-Origin: *`)
-- ✅ No database (no SQL injection risk)
-- ⚠️ Not suitable for production with sensitive data without additional hardening
-- ⚠️ Add authentication/authorization if needed
