fix(presence-service): generate prisma client in docker production stage

- Move prisma from devDependencies to dependencies so it is available
  after pnpm install --prod in the Dockerfile production stage
- Replace failed COPY of /app/node_modules/.prisma (pnpm virtual store
  path differs) with: COPY schema.prisma + RUN prisma generate in stage-1
- Only runs if schema.prisma exists (safe for all other services)
