fix(ci): fix Docker build COPY flattening and WASM wasm-opt failure

Docker: COPY crates/*/Cargo.toml crates/ flattens all Cargo.toml files
into crates/Cargo.toml (overwriting each other), causing cargo to fail
with "failed to load manifest for workspace member /code/crates/src".
Use COPY --parents with syntax=docker/dockerfile:1.7 to preserve the
subdirectory layout that the workspace crates/* glob expects.

WASM: wasm-opt bundled with wasm-pack cannot parse reference-types /
bulk-memory features from recent Rust toolchains ("Only 1 table
definition allowed in MVP"). Disable wasm-opt in wasm-test Cargo.toml.
