Problem

main is red because package-lock.json is out of sync with the workspace
manifests, so the Install dependencies step aborts before it installs anything:

npm error code EUSAGE
npm error `npm ci` can only install packages when your package.json and
package-lock.json or npm-shrinkwrap.json are in sync.
npm error Invalid: lock file's vitest@2.1.9 does not satisfy vitest@3.2.7
npm error Invalid: lock file's @vitest/coverage-v8@2.1.9 does not satisfy @vitest/coverage-v8@3.2.7
npm error Invalid: lock file's next@16.2.9 does not satisfy next@16.3.3
npm error Invalid: lock file's @stellar/stellar-sdk@15.1.0 does not satisfy @stellar/stellar-sdk@17.2.1
npm error Invalid: lock file's axios@1.15.0 does not satisfy axios@1.20.0
npm error Missing: @playwright/test@1.63.0 / playwright@1.63.0 from lock file
npm error Missing: @noble/ed25519, @noble/hashes, bignumber.js, eventsource, smol-toml, openapi-typescript, ...

This makes every workflow that installs dependencies fail on main, so unrelated
PRs cannot go green either.

Fix

Regenerated the lock against the current package.json files (root, frontend,
backend) with npm install --package-lock-only. lockfileVersion stays 3.

Verification

• before: npm ci aborts with the EUSAGE sync error above
• after: npm ci passes the sync check and installs (no EUSAGE)
• only package-lock.json changes; no manifests or source files are touched
