feat(course-package): detail page, publish/unpublish UI, edit lock

- Add detail/show page with conditional action buttons
- Route /course/course-package/detail with props query params
- List page click navigates to detail instead of edit
- Edit page redirects if package is published (published_at set)
- Store: add publish/unpublish API functions
