[Library | data-transfer-v2]: For data transfer, open full screen modal instead of alert modal | Support transfer of hierarchical files | Show description in storage types.

1. full-screen-modal.component.ts: Added cancelButton: boolean = true; and show cancel button, only if cancelButton is true and okButton is false.
2. transferData.module.ts: Imported FullScreenModalModule.
3. transferData.component.html: Replaced <modal-alert> with <fs-modal> and updated the interface accordingly | In inputs, set [inputClass]="'flat'".
4. transferData.component.ts:
   a. Configure FullScreenModal, instread of AlertModal.
   b. In destinationOptions, set label to dest.description (used to be dest.destination).
   c. In transfer, in destinations, use also element.path, to keep the initial structure/ hierarchy when transfering files.
