Fix app startup crash: add hasInstallScript to better-sqlite3 lockfile entry

package-lock.json was missing "hasInstallScript": true for better-sqlite3.
npm ci reads this flag to decide whether to run a package's install scripts;
without it, the native .node binding is never compiled and the server crashes
at startup with "Cannot find module '...better_sqlite3.node'".

Running npm install regenerates the field correctly. npm ci (used in
update-server.sh) can now compile the native module during deployment.
