Get rid of PrimeNG dependency

From major version v22 onward, PrimeNG is no longer open-source: https://primeui.dev/nextchapter

The latest version available under the MIT license is `21.1.9`. We need to remove this dependency from the `cps-ui-kit`.

The approach should look like this:
1) A quick fix to unblock the library update to Angular 22
We need to copy the PrimeNG code we use into our repo and remove the dependency. The MIT license allows this as long as we keep the copyright notices and license text. Tracked by #687
2) A long-term approach to migrate all the components/services/directives we use so they work without PrimeNG code
PrimeNG is currently used, either as utils or base components, in:
- Datepicker
- Autocomplete
- Notifications
- Dialog
- Tree autocomplete
- Tree select
- Tree table
- Table
- Menu
