create default presentation in verification controller (#470)

* create default presentation in verification controller

* Add default presentation test assertions and fix evaluatePresentation

* Add range proof test and shared setup for default presentation tests

* Add test for any credential with dateOfBirth template

* Add template4 test (skipped) and improve credential selection for multi-requirement templates

* Support multi-credential BBS+ presentations by deriving each credential separately

* Add retry logic for cheqd revocation test and update test files

* Skip cheqd revocation test (DCKA-5410)
