test(perf): record route-profile media dimensions [Codex]

[jderochervlk]

Part of #1371.

This follow-up completes the route-profile report’s media evidence without changing page behavior.

Each built profile now retains one entry per image and video with its declared source, width, and height. Missing or invalid dimensions are represented as null, alongside the existing aggregate missing-dimension counts.

The coverage verifies declared image dimensions, absent video dimensions, real production-build output, and the existing aggregate asset contract.
