fix: limit the course runs in course page to the ones in catalog

[tecoholic]

By default, the course detail page lists all the available course runs of a course for the learner to enroll. However, this exposes course runs that are not included in a enterprise catalog to the learners. In this commit, the course runs are filtered to allow only the runs mentioned in the catalog to be shown to the learner.

Testing Instructions

1. Setup the enterprise stack using the instructions from feat: allow enrolling learners on invitation only courses edx-enterprise#20
2. Create a course with at least 2 course re-runs
3. In the LMS Admin, create an Enterprise Catalog Query with {"key": ["<COURSE ID of Rerun>"]}
4. Sync the content in course-discovery, and enteprirse-catalog. (Algolia is nice, but no needed to test the changes in this PR). Make sure all the course runs in course-discovery have "Professional only" Seats with a non-zero price value.
5. Checkout the target branch of this PR
6. Add a webpack.dev.config.js

   const { getBaseConfig } = require('@edx/frontend-build');
   
   const config = getBaseConfig('webpack-dev');
   
   config.devServer.allowedHosts = "all";
   
   module.exports = config;

7. Run npm start
8. Make sure you devstack tutor domain is mapped to localhost (for example 12.0.0.1 maps to apps.local.edly.io in /etc/hosts`.
9. Without Algolia setup - visit the learner portal at http://<tutor-app-domain>:8734/test-enterprise/course/<short-course-id>. short-course-id is just the first 2 parts without the course run identified. For example in course-v1:edX+DemoCourse+2025_T1 the short ID would be edx+DemoCourse.
10. With Algolia setup - visit the learner portal's search page and select the course of the rerun added in the enterprise-catalog
11. The course detail page should show "Enroll" buttons or info boxes for as many valid course-runs.
12. Now switch to the PR branch. The enroll buttons should be reduced just one - this will target the course re-run included in the enterprise's catalog.
