Generally revise laws regarding the banking commission and the state auditor

SB 377 moves oversight of Montana's banking and financial institutions from a separate commissioner to the state auditor's office. It updates the title of the banking role to "Commissioner of Securities, Insurance, and Banking and Financial Institutions" and clarifies that the state auditor supervises this position. The bill changes how related agencies (like the Division of Banking) are monitored by legislative committees, including listing the new commissioner under the state auditor's oversight. These changes streamline regulatory structure and align agency titles with current responsibilities.
