Review: lockfile-only Dependabot bump of source-map-js 1.2.1 → 1.2.2 (frontend/yarn.lock, one entry).

• Scope: Only the resolution and integrity hash change. package.json is untouched, and the existing ^1.2.1 range already covers 1.2.2. It is a transitive dependency (PostCSS/Vite tooling), so it doesn't ship in runtime code.
• Security: Per the release notes, 1.2.2 fixes a DoS from malicious indexed source maps and a CSP unsafe-eval crash. Both are worth having.
• Risk: Low. It is a patch release. I didn't check the new integrity hash against the registry.
• Tests and changelog: No new tests are needed. A changelog.d/ fragment isn't needed for a transitive lockfile bump, though a .security.md one would be reasonable if you want the CVE fix recorded.

I didn't run the build myself. Approve once CI (frontend build and tests) is green.
