blueprints: find another way to run reconcile than with dir()

[rissson]

          Now looking at it again I think there's probably a better way to do this than using `dir()` and then `getattr()`, probably something using a decorator?

Pseudo code:

@self.reconcile
def do_something(self):
    pass

(Not really part of this PR tbh)

@BeryJu I think this has been somewhat resolved with the changes in #8454

yeah after playing around a bit with implementing this with a @ManagedAppConfig.reconcile_tenant decorator, that doesn't really help with code readability I think? It might still have an advantage to make it harder to accidentally misname a reconcile function and spend hours debugging why something isn't working
