Fix seeder: skip heavy devDeps, decouple app from seeder success

- Use npm ci --omit=dev to avoid building sharp (needs native libvips
  not available on Alpine) then install tsx separately
- Change app depends_on from seeder (service_completed_successfully)
  to relay only, so the app still starts even if seeding fails
