fix: route all console.error through ErrorHandler for consistent tracking

Converted 35+ raw console.error calls to use ErrorHandler.logError() across
12 files. ErrorHandler provides structured logging, local error storage,
and error tracking integration.

Files:
- app-selector.js: 4 errors (fetch templates, port check, suggested port, deploy)
- globals.js: 2 errors (CSRF token get/add)
- service-credentials.js: 2 errors (save/clear credentials)
- totp-settings.js: 4 errors (TOTP setup, session duration, disable, AuthCard)
- notification-settings.js: 2 errors (load config, load history)
- setup-wizard.js: 2 errors (save config to server)
- progress-tracker.js: 4 errors (storage read/write/session/fallback)
- tooltip-definitions.js: 2 errors (validation, condition eval)
- tour-manager.js: 2 errors (Driver.js not loaded, tooltip not found)
- theme-adapter.js: 1 error (theme change callback)
- weather.js: 1 error (weather update)
- onboarding.js: removed duplicate console.error, fixed 2 remaining calls

All console.error calls in the DashCaddy frontend now go through ErrorHandler.
