feat: Refactor document issuance to support multiple configurations

This commit refactors the wallet core and issuance features to support issuing multiple documents simultaneously by transitioning from single-config to list-based configuration identifiers.

Key changes include:
- Removed `IssueDocumentPartialState` in favor of the more robust `IssueDocumentsPartialState`.
- Renamed `issueDocument` to `issueDocuments` in `WalletCoreDocumentsController`, updating its parameters to accept a list of `configIds`.
- Updated `AddDocumentInteractor` and `AddDocumentViewModel` to handle the updated flow and state changes.
- Refactored internal OpenID4VCI logic to use `issueDocumentByConfigurationIdentifiers` for multi-document support.
