fabi a615b0aee7 fix(docker): unblock image builds on this host
- backend dep-cache stage stubs only main.rs/lib.rs, but Cargo.toml
  declares a second [[bin]] crawler at src/bin/crawler.rs, so
  `cargo build --locked` aborts ("can't find bin crawler"). Stub it too.
- runtime was debian:bookworm-slim (glibc 2.36) while rust:1-slim now
  tracks trixie (glibc 2.41) -> "GLIBC_2.39 not found" at boot. Pin the
  runtime to debian:trixie-slim so it matches the builder's glibc.
- frontend healthcheck probed localhost (-> musl picks IPv6 ::1) but the
  Node server binds IPv4 0.0.0.0 only -> false "unhealthy". Probe 127.0.0.1.

# 127.0.0.1, not `localhost`: musl resolves `localhost` to IPv6 ::1 first,
# but the Node server binds IPv4 0.0.0.0 only, so a localhost probe gets
# "connection refused" and the container is wrongly marked unhealthy. Use a
# GET (`-O /dev/null`) since `node build` serves 200 on `/`.
