fix(ci): add missing attachments field and crates/ dir to Dockerfiles (#1100)

The discord channel's poll_channel_mentions emit_message call was missing
the required `attachments: vec![]` field, causing WASM compilation failure.
Both Dockerfiles were also missing `COPY crates/ crates/` needed for the
extracted ironclaw_safety crate.
