fix(services): switch from Alpine to Debian slim for Prisma OpenSSL

Alpine 3.22 removed openssl1.1-compat package which Prisma needs.
Switched production stage from node:20-alpine to node:20-slim (Debian)
which has proper OpenSSL support.

Changes:
- Use node:20-slim for production stage (keep Alpine for build)
- Install openssl and wget via apt-get
- Update user creation from Alpine (addgroup/adduser) to Debian (groupadd/useradd)

Validated identity-service build and startup in WSL2:
- Build passes successfully
- NestJS starts and loads all routes
- Prisma client connects without OpenSSL errors
