Add multi-panel compliance checks + performance optimizations

Performance Improvements:
- Optimize CHECK 17 (duplicate functions) - single-pass, ~80% faster
- Add --summary mode skip for CHECK 18, 19 (expensive checks)
- Fix glob patterns in CHECK 2, 6 - use find instead of **/*.sh
- Result: 20-33% faster scans depending on mode

Multi-Panel Compliance (Checks 81-88):
- CHECK 81: Hardcoded cPanel paths (HIGH)
- CHECK 82: Missing system-detect.sh (HIGH)
- CHECK 83: Direct /var/cpanel/users access (CRITICAL)
- CHECK 84: cPanel API without validation (HIGH)
- CHECK 85: Missing case statement (MEDIUM)
- CHECK 86: Hardcoded database patterns (MEDIUM)
- CHECK 87: Missing user-manager.sh (HIGH)
- CHECK 88: No standalone fallback (LOW)

New category tags: HARDCODED-PATH, MISSING-LIB, USERDATA-ACCESS,
API-CHECK, NO-CASE, DB-PATTERN, NO-USER-MGR, NO-STANDALONE

Total checks: 80 → 88 (+10% coverage)
