In karma 6, files matched by earlier patterns aren't overridden by later
patterns. The sourceFiles patterns like `cms/**/!(*spec|djangojs).js`
matched test entry files (e.g., `cms/js/spec/main.js`) because they
don't end with "spec" or "djangojs". This prevented runFiles from
setting `included: true` on these files, so tests never started.
Split the sourceFiles patterns to precisely exclude spec/main*.js test
entry points while still serving other source files:
- Direct children of the js directory
- Subdirectories except spec/
- spec/ subdirectory, excluding main* files
This allows runFiles to control test entry point inclusion.
