Refactor core-triggered redirects

[daniel-mader]

Description

We should get rid of CurrentUserPrompt::Redirect as part of the application state and emit events to the frontend instead that contain the redirect target as a payload. This decouples the data/state of the application from the current view/route.

Motivation

See above

Requirements

n/a

Open Questions

Can we still have "predictable" redirects if they're not tracked by the state anymore or will it become a mess?

Are you planning to contribute this in a PR?
