Replace all @domain/ports/out/* imports with relative paths to fix TypeScript
compilation errors in CI/CD environment.
The issue was that TypeScript compiler (tsc) used by nest build doesn't
resolve path aliases by default. While tsconfig-paths works at runtime and
in development, it doesn't help during compilation.
Changes:
- Convert @domain/ports/out/* to relative paths (../../domain/ports/out/, etc.)
- Remove tsc-alias dependency (no longer needed)
- Revert build script to "nest build" only
This ensures the build works consistently in both local and CI/CD environments.
