Add selective error handling for DomainError in tests

[ocots]

• Create handle_solver_error utility function to selectively mark DomainError as broken
• Replace catch blocks in all test files with centralized error handling
• DomainError exceptions now mark tests as broken instead of errored
• Other exceptions are rethrown to maintain proper test failure behavior
• Add new test figures for all problems
• Extensible design allows easy addition of other exception types
