Fix setup issues and improve error messages for better user experience

[Copilot]

Problem

Users were experiencing setup failures with unclear error messages. When the backend server wasn't running, the frontend would display a generic "Login failed" message, providing no guidance on what went wrong or how to fix it. This issue was compounded by:

• No automated way to verify setup configuration
• Missing troubleshooting documentation
• Backend startup failures (often due to Prisma client not being generated)
• No proactive warnings about common misconfigurations

Solution

This PR transforms the setup and troubleshooting experience through comprehensive improvements:

1. Automated Setup Verification (verify-setup.sh)

Added a bash script that automatically checks all prerequisites and configuration:

./verify-setup.sh

Checks performed:

• ✅ Node.js v18+ and npm v9+ installed
• ✅ PostgreSQL installation and running status
• ✅ Dependencies installed (root + client)
• ✅ .env file exists and is properly configured
• ✅ Prisma client generated
• ✅ Ports 3000 and 5000 available
• ✅ Database connectivity

The script provides color-coded output with actionable suggestions for fixing any issues found.

2. Improved Frontend Error Messages

Before:

❌ Login failed

After:

❌ Cannot connect to server. The backend server is not running or is unreachable. 
   Please ensure the server is started on http://localhost:5000

Changed files:

• client/src/services/api.ts - Added network error detection and custom error formatting
• client/src/pages/LoginPage.tsx - Enhanced error handling for network failures
• client/src/pages/RegisterPage.tsx - Enhanced error handling for network failures

3. Comprehensive Troubleshooting Guide (TROUBLESHOOTING.md)

Created a 466-line guide covering:

• 8+ common issues with step-by-step solutions
• Quick diagnostic commands
• Database connection problems
• Prisma client generation errors
• Port conflicts and CORS issues
• Complete setup verification walkthrough

Each issue includes:

• Clear symptom description
• Root cause explanation
• Step-by-step solution
• Prevention tips

4. Quick Start Guide (QUICKSTART.md)

For users who want to get running quickly:

• 5-minute setup process
• Minimum required configuration
• Quick troubleshooting tips
• Command reference table

5. Helpful Startup Messages

Added proactive warnings when starting the application:

npm run dev

Now displays:

🚀 Starting ChairShare...

⚠️  WARNING: Prisma client not generated!
   Run: npx prisma generate

📍 Application will be available at:
   Frontend: http://localhost:3000
   Backend:  http://localhost:5000/api/health

💡 Tip: If you see errors, run ./verify-setup.sh to diagnose issues

6. Enhanced Documentation

Updated README.md with:

• Quick Start section at the top with fast-track commands
• Common Issues section with immediate solutions for frequent problems
• Better cross-referencing between all documentation
• Verification step added to installation instructions

Updated setup.sh with:

• Reference to verification script
• Documentation links
• Improved next steps guidance
