node:20-alpine ships OpenSSL 3.x and has no libssl.so.1.1. Without the
openssl CLI, Prisma's version detection failed and fell back to the
openssl-1.1.x engine, which then failed to load its shared library and
emitted plain text instead of JSON ("Unexpected token 'E'..."), crashing
`prisma migrate deploy` at container startup.
- Install openssl in the build and runtime stages so detection succeeds
- Pin binaryTargets to linux-musl-openssl-3.0.x so the correct engine is bundled
