fix: MobX V6 actions

[eternal-flame-AD]

Gets rid of warnings like:

[MobX] Since strict-mode is enabled, changing (observed) observable values without using an action is not allowed. Tried to modify: CurrentUser@6.loggedIn

I don't find any behavioral breakage but wrapping them in actions should be more conformant.

Only one remark, otherwise looks good.

The other actions are defined in the constructor via makeObservable. The stores should either use this or the decorator syntax and not mix between them.
