Summary

Create centralized frontend logger with level-based filtering (debug/info/warn/error)
Add sensitive data sanitization for tokens, passwords, secrets, and credentials
Support VITE_LOG_LEVEL environment variable with graceful fallback to 'info'
Logger fails silently to prevent app crashes

Fixes #84

Files Changed

Created: frontend/src/utils/logger.ts - Logger utility with sanitization
Modified: frontend/src/vite-env.d.ts - Added VITE_LOG_LEVEL type

Test Plan

npm run type-check passes
npm run lint shows no new warnings in changed files
Manual browser testing with different VITE_LOG_LEVEL values
Verify sensitive data redaction in console output
Test on mobile viewport (320px)
Test on desktop viewport (1920px)

Acceptance Criteria

VITE_LOG_LEVEL controls frontend log verbosity
Invalid VITE_LOG_LEVEL shows warning and falls back to 'info'
Sensitive data (tokens, passwords) are sanitized
Logger fails silently (no app crashes)
Works on mobile viewport (320px) - requires browser testing
Works on desktop viewport (1920px) - requires browser testing
