Complete Enhanced Triple Migration Pattern for PhotoDialog and OfferDialog components

- Implement 4-phase migration pattern: Database + SQL + Notifications + Template Streamlining
- PhotoDialog.vue: Replace databaseUtil with PlatformServiceMixin, add 8 notification constants, extract 11 computed properties
- OfferDialog.vue: Replace databaseUtil with PlatformServiceMixin, add 7 notification constants, extract CSS classes to computed properties
- Update migration template with Phase 4 (Template Streamlining) and Phase 5 (Code Quality Review)
- Add 15 centralized notification constants to src/constants/notifications.ts

Migration validation: 25/27 components complete (93% success rate)

+### [ ] 8. Add Notification Constants to Central File
+- [ ] **CRITICAL**: Add constants to `src/constants/notifications.ts` (NOT local constants)
+- [ ] Use naming pattern: `NOTIFY_[COMPONENT]_[ACTION]` (e.g., `NOTIFY_OFFER_SETTINGS_ERROR`)
 - [ ] Import constants: `import { NOTIFY_X, NOTIFY_Y } from "@/constants/notifications"`
+- [ ] **NO LOCAL CONSTANTS**: All notification text must be centralized
 
 ### [ ] 9. Replace Notification Calls

 - [ ] **Extract literals from complex modals** - Even raw `$notify` calls should use constants for text

-### [ ] 11. Template Logic Streamlining
-- [ ] **Review template** for repeated expressions or complex logic
-- [ ] **Move repeated function calls** to computed properties
-- [ ] **Simplify complex conditional logic** with computed properties
-- [ ] **Extract configuration objects** to computed properties
-- [ ] **Document computed properties** with JSDoc comments
-- [ ] **Use descriptive names** for computed properties
+## Phase 4: Template Streamlining
+
+### [ ] 11. Identify Template Complexity Patterns
+- [ ] **Repeated CSS Classes**: Long Tailwind strings used multiple times
+- [ ] **Complex Configuration Objects**: Multi-line objects in template
+- [ ] **Repeated Function Calls**: Same logic executed multiple times
+- [ ] **Complex Conditional Logic**: Nested ternary or complex boolean expressions
+
+### [ ] 12. Extract to Computed Properties
+- [ ] **CSS Class Groups**: Extract repeated styling to computed properties
+- [ ] **Configuration Objects**: Move router configs, form configs to computed
+- [ ] **Conditional Logic**: Extract complex `v-if` conditions to computed properties
+- [ ] **Dynamic Values**: Convert repeated calculations to cached computed properties
+
+### [ ] 13. Document Computed Properties
+- [ ] **JSDoc Comments**: Add comprehensive comments for all computed properties
+- [ ] **Purpose Documentation**: Explain what template complexity each property solves
+- [ ] **Organized Sections**: Group related computed properties with section headers
+- [ ] **Descriptive Names**: Use clear, descriptive names for computed properties
+
+## Phase 5: Code Quality Review
+
+### [ ] 14. Template Quality Assessment
+- [ ] **Readability**: Template is easy to scan and understand
+- [ ] **Maintainability**: Styling changes can be made in one place
+- [ ] **Performance**: Computed properties cache expensive operations
+- [ ] **Consistency**: Similar patterns use similar solutions
+
+### [ ] 15. Component Architecture Review
+- [ ] **Single Responsibility**: Component has clear, focused purpose
+- [ ] **Props Interface**: Clear, well-documented component props
+- [ ] **Event Emissions**: Appropriate event handling and emission
+- [ ] **State Management**: Component state is minimal and well-organized
+
+### [ ] 16. Code Organization Review
+- [ ] **Import Organization**: Imports are grouped logically (Vue, constants, services)
+- [ ] **Method Organization**: Methods are grouped by purpose with section headers
+- [ ] **Property Organization**: Data properties are documented and organized
+- [ ] **Comment Quality**: All complex logic has explanatory comments
