Some ETI game descriptions include the literal string <br> in metadata.
React renders descriptions as text, so the marker appears to users instead
of being treated as a line break.
Strip only the exact <br> token at the detail modal boundary. This keeps
the fix UI-only and avoids treating descriptions as HTML or normalizing any
other markup-like text.
Test Plan:
- just frontend-test
- git diff --check
