refactor: update component names to PascalCase and improve structure

- Changed component names from kebab-case to PascalCase in various files for consistency.
- Updated `<router-view>` and `<transition>` to `<RouterView>` and `<Transition>` respectively in App.vue and base-layout.vue.
- Refactored AppNaiveUIProvider.vue to use PascalCase for Naive UI providers.
- Adjusted language and theme switch buttons to use PascalCase for icon components.
- Updated button components in demo pages to use PascalCase for Naive UI buttons.
- Modified ESLint rules in route message files to use perfectionist/sort-objects for better key sorting.
- Enhanced Vite plugin files to export loadPlugin functions for better plugin management.
- Improved plugin loading logic to handle errors and warnings more effectively.
