fix: Add SSH port support and exclude deployment build from Git

- Updated .gitignore to exclude /deployment/build/ directory
- Added FTP_PORT configuration to .env.upload.example
- Enhanced upload.sh to support custom SSH ports (default 22, configurable)
- Deployment build artifacts are now properly excluded from version control

The upload script now correctly handles custom SSH ports like 2222.
