Subject: [PATCH] fix: handle AudioBackendType::Jack in settings backend name
 match

The Jack backend variant was added to qbz-audio but the backend-name
match in commands_v2/settings.rs was not updated, leaving the lib crate
non-exhaustive (E0004) and uncompilable on this branch. Add the missing
arm and sync Cargo.lock with the jack/jack-sys deps. Pre-existing breakage
unrelated to qconnect; fixed here only to unblock the build and tests.
