chore(deps): consolidate JavaScript dependency upgrades (May 2026)

[mekarpeles]

Summary

Consolidates open Renovate PRs into a single tested upgrade. All packages installed, built, and tested in Docker before opening this PR.

Note: lockfile diffs from the individual Renovate PRs could not be applied directly (master moved since they were opened). Packages were installed via targeted npm install <package>@<version> to maintain one-commit-per-package atomicity.

Packages upgraded

Package	Before	After	Severity	Closes
slick-carousel	1.6.0	1.8.1	Low — minor bump	#12639, #12758
vue	3.5.33	3.5.34	Low — patch bump	#12650
jest monorepo	30.0.5	30.4.2	Low — minor bump	#12642, #12758

Excluded packages

Package	Reason
chart.js 2.9.4 → 4.5.1 (#12761)	2-major-version jump (v2 → v4); breaking API changes expected. Needs its own PR with careful verification.
babel-loader 9 → 10 (#12760)	Major version bump; needs separate PR.
@eslint/js 9 → 10 (#12675)	Major version bump (Renovate artifact failure noted); needs separate PR.

Testing

• ✅ npm install clean
• ✅ make js: webpack compiled with 0 errors
• ✅ npm run test:js: 388 passed, 20 test suites, 0 failures
• ✅ docker compose restart web successful
• ✅ HTTP 200: home page and /search?q=test
• ✅ pre-commit clean

FYI, you can configure renovate to consolidate PRs for minor bumps like this, if you find that desirable.
