Fix: debounce fetch apps (#1021)

* Fix: debounce fetch apps

* refactor: fix AddAppForm name and add missing types

* add `use-lodash-debounce` hook to test debounce functionality

I'm planning to remove this dependency, as it requires to also install `lodash.debounce`. I prefer to implement it ad-hoc.

* refactor AddAppForm to use the observable pattern

* memoize `getAppInfoFromUrl` to prevent requesting the same information over and over

* prevent requesting data if url is not valid

* remove logging

* prevent validating form before visiting the fields

* refactor AddAppForm

reorganize code

* fix: change `any` to `unknown`

* fix: `uitls.ts` types and imports

* refactor: rename `isSubmitDisabled` to `onSubmitButtonStatusChange` prop

* refactor: rename `agreement` to `agreementAccepted`

also, moved `initialValues` to a constant `INITIAL_VALUES` outside the component

* refactor: reimplement `useDebounce` hook in-app

* refactor: extract app manifest verification to a helper function

also fixed types

* fix: prevent accessing `contentWindow` if `iframe` is `null`

* fix: `getAppInfoFromOrigin` return type

also, removed the expected type for the `getAppInfoFromOrigin` calls as it is inferred
