* Remove Service Status tab and related code

The Service Status tab and all associated files, components, and provider checkers have been deleted. References to 'service-status' have been removed from tab constants, types, and the control panel. This simplifies the settings UI and codebase by eliminating the service status monitoring feature.

* Update LocalProvidersTab.tsx

* Fix all linter and TypeScript errors in local providers components

- Remove unused imports and fix import formatting
- Fix type-only imports for OllamaModel and LMStudioModel
- Fix Icon component usage in ProviderCard.tsx
- Clean up unused imports across all local provider files
- Ensure all TypeScript and ESLint checks pass
