chore(web/frontend): remediate Dependabot vulns

[undivisible]

Failure-Class: none

• npm audit fix resolved all transitive vulnerabilities in web/frontend
• Added override floor pins: @grpc/grpc-js >=1.9.16, protobufjs >=7.6.3, @babel/core >=7.26.0, js-yaml >=4.1.1, websocket-driver >=0.5.8
• Post-fix audit: 0 vulnerabilities

Thanks for taking on the web/frontend dependency audit cleanup.

I can't accept this yet because the PR still leaves a high-severity brace-expansion audit finding in the full frontend dependency graph. I verified the current head with:

• npm ci --ignore-scripts --no-audit --no-fund — installs successfully
• npm test -- --test-reporter=spec — passes, 45 tests
• npm audit --json — still reports 1 high vulnerability: brace-expansion / GHSA-3jxr-9vmj-r5cp
• npm audit --omit=dev --json — reports 0 production vulnerabilities

So the production-only audit is clean, but the PR title/body says Dependabot vulns are remediated and “Post-fix audit: 0 vulnerabilities”; that is not true for the normal npm audit path. Please either finish the remediation for the remaining dev dependency audit finding (the affected paths include brace-expansion under eslint/minimatch/glob/typescript-eslint paths) or narrow the PR description/validation to explicitly state that only production vulnerabilities are resolved.

No supply-chain red flags found in the package tarball URLs/integrities changed here; this is a completeness/validation blocker for a dependency-security PR.

Follow-up completed

Rebased onto current main and updated the lockfile to resolve the remaining brace-expansion advisory. Local verification on the pushed head:

• npm ci --ignore-scripts --no-audit --no-fund ✅
• npm audit --package-lock-only --json → 0 findings ✅
• npm test → 45/45 passing ✅
• npm run lint ✅
• make preflight ✅

Fresh GitHub CI is now running.

Approved after the stale review finding was repaired, the branch was rebased, local preflight passed, independent gpt-5.6-terra review approved the exact rebased head, and fresh CI passed with clean full audit, tests, and lint.
