fix(js): replace console.log with centralized logger (JS-002)

Convert direct console.log/error/warn calls to use centralized logger:
- imports.js: 13 violations fixed using adminImportsLog
- vendor-themes.js: 5 violations fixed using vendorThemesLog
- code-quality-dashboard.js: 2 violations fixed using codeQualityLog
- code-quality-violations.js: 1 violation fixed using codeQualityViolationsLog
- settings.js: 1 violation fixed using settingsLog

All files now use window.LogConfig.loggers.* for consistent logging.
