refactor(memo): simplify MemoDetail error handling, drop memo.failed-to-load i18n key

The failed-to-load key was only used for non-ConnectError exceptions, which
are unreachable in practice since the Connect RPC client always wraps errors
as ConnectError. Use (error as Error).message as a plain fallback instead.
