Move e2e test apps to prod

### Description

Most of the apps we use for end to end testing har currently hosted in the dev environment.
This env is considered unstable as @Altinn/team-studio us it for testing.

See this slack convo: https://digdir.slack.com/archives/C0760NPT2BE/p1723556124119149

We therefore need to move our e2e testing apps to prod.

### Tasks

- move repos to prod
- deploy apps to prod
- update app-frontend-react urls

### Acceptance Criterias

- All repos moved to prod
- All apps moved and deployed to prod
- app-frontend-react updated with the correct urls to the testing apps
- Github actions updated with new locations
- All e2e tests passing with the apps running in prod

Start by locating the end-to-end test app references, app-frontend-react URLs, and GitHub Actions workflows that point to the dev environment. Move the repositories and deployments to prod, update the testing-app URLs and workflow locations, then run the full e2e suite to confirm all tests pass against the prod apps.
