[CONTRACT][DATA_SOV] Display of contracts of not successful data consumption (tombstones)

[mkanal]

As an administrator, I am responsible for compliance,
I want to be able to view the contracts that have not been successfully exchanged via the EDC due to missing or invalid policies,
so that I can see which assets could not be consumed due to missing or insufficient policies

Link

• relates to [CONTRACT][DATA_SOV] Display of contracts in the Contract View that were concluded during the exchange of notifications via the EDC #985

Hints / Details

Acceptance Criteria

• User is able to identify/filter for contract where contract negotiation was not successful (tabs are suitable as well for parts/notifications/tombstones)
• User gets a clear UI feedback that the contract is not linked to any asset
• Tombstones are visualized in the same manner as in parts table

    participant EDC_S as "EDC Supplier"
    participant  PolicyStore 

    Superior --> Trace_X: Send notification
    Trace_X --> EDC_S : Get Notification CatalogOffer of EDC_S 
    EDC_S -->> Trace_X : return CatalogOffer 
    Trace_X --> PolicyStore : Get Policy for BPNL or default 
    Trace_X --> Trace_X: check Policy of CatalogOffer with Policy defined for BPNL

Add example for a tombstone in IRS for Contract Aggreement

[ds-mwesener]

Hi @mkanal since we had a discussion in: #985. We figured out that we will not have contracts for failed negotiations. We agreed on displaying information within part detail view and notification detail view.

Can we close this story, or change this story to reflect the goal? We need to make sure to display the tombstone info within the parts detail view.
