[refactor] Improve settings domain organization (#5550)

* refactor: move settingStore to platform/settings

Move src/stores/settingStore.ts to src/platform/settings/settingStore.ts
to separate platform infrastructure from domain logic following DDD principles.

Updates all import references across ~70 files to maintain compatibility.

* fix: update remaining settingStore imports after rebase

* fix: complete remaining settingStore import updates

* fix: update vi.mock paths for settingStore in tests

Update all test files to mock the new settingStore location at
@/platform/settings/settingStore instead of @/stores/settingStore

* fix: resolve remaining settingStore imports and unused imports after rebase

* fix: update settingStore mock path in SelectionToolbox test

Fix vi.mock path from @/stores/settingStore to @/platform/settings/settingStore
to resolve failing Load3D viewer button test.

* refactor: complete comprehensive settings migration to platform layer

This commit completes the migration of all settings-related code to the platform layer
as part of the Domain-Driven Design (DDD) architecture refactoring.

- constants/coreSettings.ts → platform/settings/constants/coreSettings.ts
- types/settingTypes.ts → platform/settings/types.ts
- stores/settingStore.ts → platform/settings/settingStore.ts (already moved)

- composables/setting/useSettingUI.ts → platform/settings/composables/useSettingUI.ts
- composables/setting/useSettingSearch.ts → platform/settings/composables/useSettingSearch.ts
- composables/useLitegraphSettings.ts → platform/settings/composables/useLitegraphSettings.ts

- components/dialog/content/SettingDialogContent.vue → platform/settings/components/SettingDialogContent.vue
- components/dialog/content/setting/SettingItem.vue → platform/settings/components/SettingItem.vue
- components/dialog/content/setting/SettingGroup.vue → platform/settings/components/SettingGroup.vue
- components/dialog/content/setting/SettingsPanel.vue → platform/settings/components/SettingsPanel.vue
- components/dialog/content/setting/ColorPaletteMessage.vue → platform/settings/components/ColorPaletteMessage.vue
- components/dialog/content/setting/ExtensionPanel.vue → platform/settings/components/ExtensionPanel.vue
- components/dialog/content/setting/ServerConfigPanel.vue → platform/settings/components/ServerConfigPanel.vue

- ~100+ import statements updated across the codebase
- Test file imports corrected
- Component imports fixed in dialog service and command menubar
- Composable imports updated in GraphCanvas.vue

```
src/platform/settings/
├── components/          # All settings UI components
├── composables/         # Settings-related composables
├── constants/          # Core settings definitions
├── types.ts           # Settings type definitions
└── settingStore.ts    # Central settings state management
```

✅ TypeScript compilation successful
✅ All tests passing (settings store, search functionality, UI components)
✅ Production build successful
✅ Domain boundaries properly established

This migration consolidates all settings functionality into a cohesive platform domain,
improving maintainability and following DDD principles for better code organization.
