Clean up repository - remove unused files and consolidate documentation

Removed:
- MIGRATION_PLAN.md, MIGRATION_ROADMAP.md, NEXT_STEPS.md (old planning docs)
- IMPLEMENTATION_SUMMARY.md, USER_GUIDE.md (redundant)
- frontend/src/ - unused React SPA code (using Flask templates instead)
- frontend/build/ - old build artifacts
- frontend/public/, frontend/node_modules/ - dependencies
- backend/utils/helpers.py - unused utility functions
- backend_fastapi/ - unused FastAPI backend (using Flask instead)
- FileFlow/FIXES.md - redundant

Updated:
- COMMANDS.txt - Clean, concise quick start guide
- README.md - Updated to reflect current status
- Documented production deployment steps
- Clear project structure documentation

Result:
- Reduced repository size significantly
- Clear single source of truth for setup (COMMANDS.txt)
- Only necessary code and documentation remains
- Easier for new contributors to understand project

-FileFlow Application - Terminal Commands to Run
+                        FILEFLOW - QUICK START GUIDE
 ================================================================================
 
-IMPORTANT: Run these commands in SEPARATE TERMINALS in the specified order.
+FILEFLOW is a Google Drive clone built with Flask backend and template rendering.
 
 ================================================================================
-TERMINAL 1: Start Flask Backend
+                            INSTALLATION & SETUP
 ================================================================================
 
-cd /home/amitdevx/codes/FileFlow/FileFlow
+1. CREATE PYTHON VIRTUAL ENVIRONMENT:
+   
+   cd /home/amitdevx/codes/FileFlow/FileFlow
+   python3 -m venv backend/venv
+   backend/venv/bin/pip install -r backend/requirements.txt
 
-export FLASK_APP=backend.app
-export FLASK_ENV=development
-export SECRET_KEY=testsecretkey123
+2. INITIALIZE DATABASE:
 
-backend/venv/bin/flask run --host=0.0.0.0 --port=5000
-
-Expected Output:
-  * Running on http://0.0.0.0:5000
-  * Debug mode: on
-
-Wait for "Running on http://0.0.0.0:5000" before proceeding to Terminal 2.
+   backend/venv/bin/python -c "from backend.app import app, db; \
+   app.app_context().push(); db.create_all()"
 
 ================================================================================
-TERMINAL 2: Start React Frontend (in new terminal)
+                            RUNNING THE APPLICATION
 ================================================================================
 
-cd /home/amitdevx/codes/FileFlow/FileFlow/frontend
+START FLASK BACKEND (Terminal 1):
 
-npm start
+   cd /home/amitdevx/codes/FileFlow/FileFlow
+   export FLASK_APP=backend.app
+   export FLASK_ENV=development
+   export SECRET_KEY=your-secret-key-here
+   backend/venv/bin/flask run --host=0.0.0.0 --port=5000
 
-Expected Output:
-  webpack compiled successfully
-  Compiled successfully!
-  You can now view frontend in the browser.

-TROUBLESHOOTING
+                            TROUBLESHOOTING
 ================================================================================
 
-If Flask doesn't start:
-  - Check if port 5000 is already in use: lsof -i :5000
-  - Kill existing process: kill -9 <PID>
-  - Make sure SECRET_KEY is set (see export commands above)
+FLASK WON'T START:
+- Check port 5000 isn't in use: lsof -i :5000
+- Kill existing process: kill -9 <PID>
+- Ensure SECRET_KEY is set (export SECRET_KEY=...)
 
-If React doesn't compile:
-  - Delete node_modules: rm -rf node_modules
-  - Reinstall: npm install
-  - Try again: npm start
+FILES NOT SHOWING AFTER UPLOAD:
+- Verify Flask is running on :5000
+- Refresh page: Ctrl+F5 (hard refresh)
+- Check database at instance/fileflow.db
 
-If files.map error in React:
-  - Make sure you're visiting http://localhost:5000, not :3000
-  - Clear browser cache: Ctrl+Shift+Delete
+PAGES SHOW BLANK:
+- Clear browser cache
+- Check CSS loads: View page source, verify /static/css/styles.css
+- Check Flask error log: tail /tmp/flask.log
 
-If upload/rename/delete doesn't work:
-  - Make sure Flask is running on port 5000
-  - Check Flask terminal for errors
-  - Refresh page: Ctrl+F5 (hard refresh)
-
-Database:
-  - SQLite database at: /home/amitdevx/codes/FileFlow/FileFlow/instance/fileflow.db
-  - To reset: rm instance/fileflow.db && python -c "from backend.app import app, db; app.app_context().push(); db.create_all()"
+LOGIN REDIRECTS TO BLANK PAGE:
+- Make sure you're on http://localhost:5000 not :3000
+- Log out and login again
+- Clear session cookies

-TESTING WITHOUT UI (Curl Commands)
+                            PRODUCTION DEPLOYMENT
 ================================================================================
 
-SIGNUP:
-  curl -X POST http://localhost:5000/signup \
-    -H "Content-Type: application/x-www-form-urlencoded" \
-    -d "username=testuser&email=test@example.com&password=password123"
+For production use:
 
-LOGIN:
-  curl -X POST http://localhost:5000/login \
-    -c cookies.txt \
-    -H "Content-Type: application/x-www-form-urlencoded" \
-    -d "username=testuser&password=password123"
+1. Change SECRET_KEY to strong random value
+2. Set FLASK_ENV=production
+3. Use production WSGI server (gunicorn, uWSGI)
+4. Set up HTTPS/SSL certificate
+5. Use PostgreSQL instead of SQLite
+6. Enable logging and monitoring
+7. Set up backup strategy for database
 
-LIST FILES:
-  curl http://localhost:5000/api/files \
-    -b cookies.txt \
-    -H "Accept: application/json"
+Example production start:
+   export FLASK_ENV=production
+   export SECRET_KEY=$(python3 -c 'import secrets; print(secrets.token_hex(32))')
+   gunicorn -w 4 -b 0.0.0.0:5000 "backend.app:app"
 
-UPLOAD FILE:
-  curl -X POST http://localhost:5000/upload \
-    -b cookies.txt \
-    -F "file=@/path/to/file" \
-    -F "folder_id=1"
