fix(ci): hoisted node_modules + alpine binary target for Prisma in Docker

Root cause (from build log):
1. Prisma 6 generates client into @prisma/client package dir (not .prisma/client)
2. pnpm default isolated linker puts everything in .pnpm/ store with symlinks
   at top-level — Docker COPY of @prisma followed broken/incomplete symlinks
3. node:22-alpine needs linux-musl-openssl-3.0.x engine binary

Fixes:
- .npmrc: node-linker=hoisted → flat node_modules, COPY behaves like npm
- schema.prisma: add linux-musl-openssl-3.0.x to binaryTargets
- Dockerfile: drop dead .prisma/client checks, copy only @prisma (where
  Prisma 6 actually writes the client) plus standalone output
