Add comprehensive report generation to batch analyzer

- Prompts user to save detailed report after analysis
- Generates formatted text report with full domain breakdown
- Includes server info, domain analysis, summary, and recommendations
- Shows memory impact, traffic data, and optimization potential
- Saves to /tmp with timestamp for easy reference
- Provides actionable recommendations based on findings
