spec: add proposals for debug logging cleanup and i18n completion

Two new proposals from comprehensive QA review:

1. cleanup-debug-logging
   - Remove 60+ console.log/error statements from frontend
   - Create environment-aware logging utility
   - Prevent sensitive data exposure in browser console

2. complete-i18n-coverage
   - Add missing translations to WeeklyReportPreview
   - Add missing translations to ReportHistory
   - Add missing translations to AuditPage modal
   - Use dynamic locale for date formatting
