Fix Zoho connection issues and add local testing capabilities

- Fixed 'days_back' parameter error in zoho_client.py
- Added robust settings validation in app.py to prevent int() errors
- Created LOCAL_TESTING.md with comprehensive testing guide
- Added run_local.sh for easy local server setup
- Added deploy_updates.sh for deployment instructions
- Added test_local_connection.py for automated testing
- Updated config.json with proper structure
- All fixes tested and working locally

+# Local Testing Guide
+
+This guide helps you test the Email Alerts Application locally.
+
+## 🚀 Quick Start
+
+### Option 1: Use the automated script
+```bash
+./run_local.sh
+```
+
+### Option 2: Manual setup
+```bash
+# Activate virtual environment
+source venv/bin/activate
+
+# Install dependencies
+pip install -r requirements.txt
+
+# Start the server
+python run_server.py
+```
+
+## 🌐 Access the Application
+
+Once the server is running, you can access:
+
+- **Dashboard**: http://localhost:5237/
+- **Settings**: http://localhost:5237/settings
+
+## 🧪 Testing the Connection
+
+### Step 1: Configure Credentials
+1. Go to http://localhost:5237/settings
+2. Enter the Zoho credentials:
+   - **Email**: `projects@manaknightdigital.com`
+   - **Password**: `4o%!sbk$(3!>@#567!!`
+3. Click "Save Settings"
+
+### Step 2: Test Connection
+1. Click "Test Connection" button
+2. You should see: "Connection successful! Found X emails in the last 7 days."
+
+## 🔧 Troubleshooting
+
+### If you get "days_back" error:
+- The server is running old code
+- Restart the server: `Ctrl+C` then run `./run_local.sh` again
+
+### If you get "ModuleNotFoundError":
+- Make sure you're using the virtual environment: `source venv/bin/activate`
+
+### If port 5237 is in use:
+- The script will automatically kill existing processes
+- Or manually: `pkill -f "python.*run_server.py"`
+
+## 📋 Test Checklist
+
+- [ ] Server starts without errors
+- [ ] Web interface loads at http://localhost:5237/
+- [ ] Settings page loads at http://localhost:5237/settings
+- [ ] Can enter Zoho credentials
+- [ ] "Test Connection" works without "days_back" error
+- [ ] Connection shows "successful" message
+
+## 🎯 Expected Results
+
+✅ **Success**: "Connection successful! Found X emails in the last 7 days."
+❌ **Old Error**: "Connection failed: ZohoClient.fetch_emails() got an unexpected keyword argument 'days_back'"
+
+## 🛑 Stopping the Server
+
+Press `Ctrl+C` in the terminal where the server is running.
+
+## 📁 Files for Testing
+
+- `run_local.sh` - Automated local startup script
+- `test_local_connection.py` - Connection test script
+- `zoho_client.py` - Fixed with days_back parameter
+- `config.json` - Clean configuration (no hardcoded credentials)
