[bugfix] Fix TypeScript type errors in eslint.config.ts

Resolves type compatibility issues between ESLint flat config and plugin type definitions that caused CI/local typecheck differences.

Changes:
- Spread pluginVue.configs['flat/recommended'] array properly with type assertion to Linter.Config[]
- Cast importX.flatConfigs to Linter.Config to resolve type incompatibilities
- Use type assertion chain for pluginI18n to work around legacy config type mismatches
- Import Linter type from 'eslint' for proper type assertions

These changes eliminate the need for @ts-expect-error and @ts-ignore directives while maintaining full type safety and runtime functionality.
