Fix: replace @/* path alias with relative imports for Docker compat

Vite's path alias resolution worked locally but consistently failed in
the Docker stage with "Could not load /web/src/lib/utils ... ENOENT"
even after fixing __dirname for ESM. Some interaction between act/buildx
and Vite's resolver around tsconfig paths. Relative imports sidestep the
issue entirely and are explicit about the dependency direction.
