Get merge request conflicts

Returns the list of conflicting configurations between the source (dev) branch and the target (default) branch of the merge request. A conflict means the merge cannot proceed without resolving it (for example, the configuration was changed in both the dev branch and the default branch since the dev branch last took it from the default branch, i.e. branch creation, rebase or reset to default; in projects with a protected default branch any change in the default branch counts).

The endpoint is primarily intended for UI consumption — callers can detect conflicts before attempting a merge. An empty array means the merge request can be merged without conflicts.
