Improve Contract Definition Creation

Description

Creating Contract Definitions should be reworked. Right now you need to make up an ID, etc.

• Add a "confirmation dialog": "Do you want to publish your asset?" When successfully having created an asset.
• The ID should then be prefilled as "cd-{{ ASSET_ID }}"
• Only one policy field should be available "Who can see the data offer / When can you transfer the data?".
• A "Button" similar to the ones in the asset creation to toggle things should be added "Use different policies for data offer visibility and transfer inititation". A button over a check box for UX consistency.
• If the above state is toggled two policy selects are shown again "Who can see the data offer?" "When can you transfer the data?"
• The policy select component should get a button (use flex row on the component DOM element via @HostBinding("class.flex") @HostBinding("class.flex-row") @HostBinding("class.space-x-[5px]") cls = true;, "Create Policy". With this button you should be able to create a policy on the fly, that will then be auto selected by the boxes.
• The always-true policy should be selected by default.
• If you truly created a contract definition for your asset successfully, you should be redirected to the contract definition page.
