Christian Gick 62be6b91d6 fix(e2ee): patch Rust FFI HKDF to match Element Call JS SDK parameters ...

EC JS SDK uses: salt=Uint8Array(8), info=encode("LKFrameEncryptionKey")
Rust FFI used: salt=ratchet_salt, info=[0u8;128]

The salt and info parameters were swapped, causing DEC_FAILED on every
call. This patch fixes the Rust HKDF derivation in the Dockerfile
before cargo build.
