032: fix missing await on git_service.get_status() (async -> coroutine)

git_service.get_status() is async def, but was called without await,
returning a coroutine object instead of dict. The coroutine was then
used as a dict value in RepoStatusBatchResponse, causing Pydantic
ValidationError (dict type mismatch).
