Subject: [PATCH] fix(docker): touch source files to force cargo recompilation

Docker COPY preserves original file timestamps, which can be older than
the dummy-source binary compiled in the dependency caching layer. Cargo
sees the sources as unchanged and skips recompilation, producing a 329KB
empty binary instead of the real web server.
