fix: upgrade to Node 22 and fix npm lockfile incompatibility

Lockfile generated by local npm 11 was incompatible with npm 10
(bundled in node:20-alpine), causing npm ci to fail with missing
packages. Switch to node:22-alpine and use npm install instead of
npm ci to tolerate cross-version lockfiles.
