Modernize language in a civil procedure statute

LB 1100 updates Nebraska's civil court procedures by removing outdated legal distinctions between "actions at law" and "suits in equity." It replaces these terms with a single unified process called a "civil action" for all non-criminal court cases. This change directly affects Nebraska courts, lawyers, and anyone involved in filing or defending civil lawsuits. The bill modernizes court language without altering substantive legal rights or procedures, simply streamlining terminology to reflect current practice.
