Add port availability check to setup scripts

Before starting Docker containers, setup scripts now check if required
ports are available and warn users about conflicts.

Features:
- Checks all required ports: 8080, 8025, 1025, 6379
- Checks database port based on selection (3306 for MySQL, 5432 for PostgreSQL)
- Shows clear status for each port (Available/In Use)
- If conflicts found:
  - Displays warning message
  - Shows helpful commands to find and stop conflicting processes
  - Asks user if they want to continue anyway
  - Exits if user chooses not to continue

Benefits:
- Prevents confusing 'port already in use' errors during container startup
- Provides clear diagnostic information
- Gives users control over how to handle conflicts
- Improves setup experience and reduces frustration

Implementation:
- setup.bat: Uses netstat with findstr for Windows
- setup.sh: Uses lsof and netstat for Linux/Mac compatibility

setup.sh
