Fix Python syntax error and add service recovery guide

1. Fixed f-string syntax error in api_import.py line 1036-1038
   - Extracted backslash replacements to variables before f-string
   - This prevented the app from starting due to SyntaxError

2. Created FIX_MISSING_SERVICES.md guide to help users:
   - Diagnose and fix services with missing file paths
   - Options for deleting, reimporting, or fixing broken services
   - Instructions for GitHub import and auto-discovery

+# Fix Missing Service Files
+
+## Problem
+Your dashboard shows 7 services that can't start because their files/directories don't exist:
+
+1. Forensic_CPA_AI (port 5000)
+2. Pearson_Nexus_AI_NEW-main (port 3040)
+3. ai-financial-advisor (port 3009)
+4. pearson-nexus-ai-monorepo (port 3030)
+5. prototype (port 3003)
+6. rest-express (port 3012)
+7. retail-commission-tracker (port 3050)
+
+## Solution Options
+
+### Option 1: Delete All Broken Services and Start Fresh
+
+**Via Dashboard UI:**
+1. Go to http://localhost:5010/services
+2. Click on each service
+3. Click "Delete" button on each service
+4. Then import fresh bundles or use auto-discovery
+
+**Via API (if you have curl):**
+```bash
+# Get service IDs
+curl http://localhost:5010/api/services
+
+# Delete each service by ID
+curl -X DELETE http://localhost:5010/api/services/1
+curl -X DELETE http://localhost:5010/api/services/2
+# ... repeat for all services
+```
+
+### Option 2: Clone/Download Missing Repositories
+
+If you have the repositories on GitHub or elsewhere:
+
+```bash
+# Create a repositories folder
+mkdir -p ~/repositories
+
+# Clone your projects
+cd ~/repositories
+git clone https://github.com/YOUR_USERNAME/Forensic_CPA_AI.git
+git clone https://github.com/YOUR_USERNAME/Pearson_Nexus_AI_NEW-main.git
+git clone https://github.com/YOUR_USERNAME/ai-financial-advisor.git
+git clone https://github.com/YOUR_USERNAME/pearson-nexus-ai-monorepo.git
+git clone https://github.com/YOUR_USERNAME/prototype.git
+git clone https://github.com/YOUR_USERNAME/rest-express.git
+git clone https://github.com/YOUR_USERNAME/retail-commission-tracker.git
+
+# Then use auto-discovery to re-import them
+# Go to: http://localhost:5010/import
+# Use "Import from folder" with path: /home/user/repositories
+```
+
+### Option 3: Use GitHub Import Feature
+
+If you have a GitHub token:
+
+1. Go to http://localhost:5010/import
+2. Click "Connect GitHub (mobile)" to authenticate
+3. Click "Load my repos" to see all your repositories
+4. Select each repository and import it
+5. The system will clone them locally and register them
+
+### Option 4: Import from Bundles
+
+If you have `.json` bundle files:
+
+1. Go to http://localhost:5010/import
+2. Drag and drop the `.json` bundle files
+3. Or use "Import bundle" and paste the JSON
+
+## Recommended Approach
+
+**For best results:**
+
+1. **Delete all broken services** (Option 1)
+2. **Connect GitHub** and use auto-import (Option 3), OR
+3. **Clone repos manually** then use auto-discovery (Option 2)
+
+## Quick Commands
+
+```bash
+# Check what directories you have
+ls -la ~/repositories 2>/dev/null || echo "No repositories folder"
+ls -la ~/Documents 2>/dev/null || echo "No Documents folder"
+ls -la ~ | grep -i pearson
+ls -la ~ | grep -i forensic
+
+# Create a workspace for your projects
+mkdir -p ~/repositories
+cd ~/repositories
+
+# After cloning/downloading projects, verify they exist
+ls -la ~/repositories
+```
+
+## Need Help?
+
+If you're not sure which option to choose, answer these questions:
+
+1. **Do you have GitHub repos for these projects?** → Use Option 3
+2. **Do you have the code on another computer?** → Copy it over, then use Option 2
+3. **Do you have .json bundle files?** → Use Option 4
+4. **Starting completely fresh?** → Use Option 1, then import as needed
+
+## Next Steps
+
+After fixing the services:
+
+1. Verify paths are correct: http://localhost:5010/services
+2. Install dependencies for each service (npm install, pip install, etc.)
+3. Start services from the dashboard
+4. Check for port conflicts and resolve them
