Move @nestjs/config to runtime deps so the deployed image can find it

app.module.ts imports @nestjs/config at runtime, but it was listed
under devDependencies. pnpm deploy --prod correctly stripped it,
producing a runnable-shaped image that crashes on boot with
`Cannot find module '@nestjs/config'`. Move it to dependencies and
let the lockfile reclassify accordingly.

Bump backend and frontend to 0.1.4. Frontend has no functional change
— forced bump to satisfy the per-service push gate in CI.
