Handle BadRequestException and improve test robustness

Added handling for BadRequestException in RecActionProcedureTests
to ensure data-related errors are gracefully handled. Updated
UpdateActionProcedure_runs_via_mediator to use UpdateActionDto
for better type safety. Refactored ReadRecActionViewQuery_returns_actions_for_profile
to dynamically resolve profile IDs, improving test reliability
and providing clearer feedback when test data is missing.
