Unify natspec asterisks identation

[arwer13]

Unify across all the contracts.

E. g. in the snippet below the asterisks are aligned at the middle symbol of /** but there are also cases where they are aligned at the first or at the second.

 /**
  * @notice Returns internal info about stake limit
  * @notice Returns full info about current stake limit params and state

Looks like we are going to use /// for natspec.
