fix: apply DB projection after Tangled morphism Tangled records were only getting the morphism (field rename) but not the DB projection (AT-URI decomposition into repo_did/repo_name). This caused all Tangled issues and pulls to have empty repo_did and repo_name fields, making them invisible on repo pages.
