Pull Request Overview

This PR improves custom URL handling in the HTML exporter by refactoring tests to use dynamically generated URLs from the ADR instance instead of hardcoded legacy URLs. The changes remove support for legacy literal paths (/static/ and /media/) in favor of configured custom URLs, making the exporter more flexible and less dependent on hardcoded assumptions.

• Replaces hardcoded /static/ and /media/ paths in tests with dynamic URLs from adr_serverless.static_url and adr_serverless.media_url
• Removes legacy literal path support from the HTML exporter implementation
• Simplifies URL pattern matching by focusing on configured custom URLs and versioned Ansys paths
