Fix security issues and QA false positives

Security fixes in lib/mysql-analyzer.sh:
- Added -- separator to grep/sed/awk/wc commands to prevent filename injection
- Fixed 10 ESCAPE issues (lines 130, 153, 180, 208, 210, 320, 324, 405, 507, 513)

QA script improvements in tools/toolkit-qa-check.sh:
- Updated ESCAPE check (CHECK 66) to recognize -- as safe pattern
- Updated HARDCODED-PATH check (CHECK 81) to skip control panel abstraction libraries
- Now correctly excludes domain-discovery.sh, plesk-helpers.sh, user-manager.sh from hardcoded path warnings
- Reduced false positives by ~23 issues
