Introduce ESLint rule to discourage unsafe as assertions with useParams()

**Is your feature request related to a problem? Please describe.**

In the frontend codebase, route parameters obtained from `useParams()` are sometimes forcefully type-asserted using `as`, for example:

```ts
const { programKey, moduleKey } = useParams() as {
programKey: string
moduleKey: string
}

```
