fix: JWT kid/jku lessons (#1949)

* refactor: rewrite hints

Use active voice and fix grammar issues.

* fix: use Thymeleaf `th:action`

* fix: JWT kid/jku lessons

Split the JavaScript into two files they pointed to the same URL

The JWTs are now valid, they parse successfully.

The paths now include `/kid` and `/jku` to make sure the hints match accordingly in the UI. Otherwise `/delete` would pick up both hints from both assignments as the paths overlap.

Closes: #1715

* fix: update to latest pre-commit version

* fix: increase timeouts for server to start during integration tests
