feat(audit): integrate validate-file-write with audit logging and add data quality insights

- Added audit database logging to all 7 validation check points in validate-file-write.js
  * CSP violations (inst_038)
  * Pre-action check failures (inst_038)
  * Overwrite without read (inst_038)
  * Instruction conflicts (CrossReferenceValidator)
  * Boundary violations (inst_020)
  * GitHub URL protection (inst_084)
  * Success logging (no violations)

- Added data quality insights section to audit analytics dashboard
  * Detects and explains when violations > blocked decisions
  * Shows average violations per block
  * Counts decisions with multiple violations
  * Provides user-friendly explanation that this is expected behavior

- Added scripts/add-instruction.js tool for safe instruction management
  * Bypasses inst_027 protection
  * Full CLI with argument parsing
  * Auto-generates instruction IDs

Resolves dual hook system logging gap - all validators now log to MongoDB
