Enhance analyze_all_domains output to show passed checks

Users requested visibility into what was checked and found OK, not just failures.

Changes:
- Show issue breakdown by severity (CRITICAL, HIGH, MEDIUM, LOW)
- Display which checks passed (max_children OK, memory OK, timeouts OK)
- For domains with no issues: 'All checks passed (max_children, memory, timeouts, config)'
- Color-coded summary for better readability

Example output:
  [1] Analyzing: pickledperil.com
      ✗ Issues found: 1 HIGH
        [HIGH] PERFORMANCE: OPcache is disabled
      ✓ Checks passed: max_children OK, memory OK, timeouts OK
