CI: fix format-check failures (58 format + 33 import-order)

[Trosper3]

Problem

The format-check CI job is failing: 58 formatting violations and 33 import-order violations across ~30+ files (e.g. Tools/Constants.js, components/ContributorCard.js, components/Visualization/**, biome.json itself).

Fix

All of these are auto-fixable. Run:

npm run format

(= biome check --write .) and commit the result. Verified locally as a dry run — it resolves all 58 format + 33 import-order findings with no manual edits needed.

Notes

• Zero-risk mechanical change; review the diff for line-ending noise before committing.
• biome.json reports it was authored against an older Biome schema (2.5.3 vs installed 2.5.8) — consider running biome migrate in the same pass.
