feat: Implement comprehensive edit functionality and standardize UI components

• Add full edit functionality for groceries with modal support
• Standardize delete confirmations across all components using ConfirmDeleteModal
• Implement complete shopping event edit functionality:
  - Create EditShoppingEvent component with full form capabilities
  - Add missing backend PUT endpoint for shopping events
  - Support editing all event data (shop, date, groceries, amounts, prices, notes)
• Add inline grocery edit functionality in shopping event forms:
  - Allow editing grocery items within add/edit forms
  - Load selected items back into input fields for modification
• Fix date timezone issues in edit forms to prevent date shifting
• Remove non-functional "View Details" button in favor of working Edit button
• Enhance user experience with consistent edit/delete patterns across the app

Breaking changes: None
Backend: Added PUT /shopping-events/{id} and DELETE /shopping-events/{id} endpoints
Frontend: Complete edit workflow for all entities with improved UX
