Dries Peeters 01459f6d3b feat: Implement comprehensive onboarding and enhanced error handling
- Interactive tour system with 13-16 comprehensive steps covering all
  major features
- Tooltip system for complex features (auto-attaches to elements with
  data-tooltip attribute)
- Contextual help buttons on complex features (Kanban, Reports,
  Analytics, Invoices, Time Entry)
- Feature discovery system with visual badges for power features
- Enhanced tour content with keyboard shortcuts, tips, and actionable
  guidance
- Smart element finding with auto-expansion of hidden dropdowns
- Proper tooltip positioning with viewport-aware placement

### Error Handling Features (Section 15)

- User-friendly error messages for all HTTP status codes (400, 401, 403,
  404, 409, 422, 429, 500, 502, 503, 504)
- Retry buttons for failed operations with exponential backoff
- Offline mode indicators with visual queue count display
- Offline operation queue with automatic processing when connection
  restored
- Graceful degradation with feature detection and fallbacks
- Recovery options in error pages (Dashboard, Back, Refresh, Login)
- Enhanced error templates with retry buttons and recovery actions

### Technical Improvements

- Added /api/health endpoint for connection monitoring
- Improved fetch interceptor for automatic error handling
- Network status monitoring with periodic health checks

- Styled keyboard shortcuts (kbd) and emphasized text (strong) in
  tooltips
