chore(deps): upgrade react-router-dom to 7.18.1, bump postcss and brace-expansion

Clears GHSA-337j-9hxr-rhxg and GHSA-wrjc-x8rr-h8h6 (no 6.x backport) plus
GHSA-jjmj-jmhj-qwj2, which has no patch at all on the react-router-dom 6.30.x
line. Drops the now-unused @remix-run/router resolution.

Also pins postcss 8.5.23 (GHSA-r28c-9q8g-f849, GHSA-6g55-p6wh-862q) and adds
the brace-expansion ^5.0.5 descriptor, which was still resolving to 5.0.6.
