feat(cli-endpoints): add create, update, and delete functionality for CLI endpoints

- Implemented `useCreateCliEndpoint`, `useUpdateCliEndpoint`, and `useDeleteCliEndpoint` hooks for managing CLI endpoints.
- Added `CliEndpointFormDialog` component for creating and editing CLI endpoints with validation.
- Updated translations for CLI hooks and manager to include new fields and messages.
- Refactored `CcwToolsMcpCard` to simplify enabling and disabling tools.
- Adjusted `SkillCreateDialog` to display paths based on CLI type.
