fix(frontend/deps): resolve fast-uri and svgo high-severity advisories

[cristim]

Summary

Clears the two newly-published high-severity npm advisories that are currently failing Security Scanning on main HEAD, which blocks every open PR in the repo.

Advisory	Package	Affected	Fixed	Path (transitive)
GHSA-v2hh-gcrm-f6hx	fast-uri	3.0.0-3.1.3	3.1.4	via ajv (ajv-formats / schema-utils, webpack tooling)
GHSA-2p49-hgcm-8545	svgo	4.0.0-4.0.1	4.0.2	via postcss-svgo (css-minimizer-webpack-plugin / cssnano)

Fix method

Both are transitive dev-dependencies. The fixed patch versions already satisfy the existing semver ranges (^3.0.1, ^4.0.1), so npm audit fix bumps only package-lock.json (6 lines). No package.json change or overrides block was needed, no downgrades, no breaking major bumps.

npm audit now reports 0 vulnerabilities.

Verification

• npm audit: 0 vulnerabilities (both target advisories gone)
• npm ci: exit 0
• npm run build (webpack): success
• npm test (jest): 2714 passed, 1 skipped
• tsc --noEmit: clean
• eslint: 0 errors

Impact

This unblocks Security Scanning across main and all currently-open PRs, so it is high-priority to merge.

Important

Review skipped

Review was skipped due to path filters

⛔ Files ignored due to path filters (1)

• frontend/package-lock.json is excluded by !**/package-lock.json

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.
