[FIX] account_ux: handle list domain in open_invalid_statements_action

The domain returned by super() may already be a Python list instead of
a string representation. Calling safe_eval() on a list raises a TypeError.

Added an isinstance check to only evaluate the domain if it is a string,
keeping the existing behavior for string domains while supporting list domains.

closes #969
