MS Student Funding Formula; clarify to remove obsolete references to MAEP funding.

HB 1620 updates Mississippi's education funding terminology by removing outdated references to the "Mississippi Adequate Education Program" (MAEP) and replacing them with current language describing the "Mississippi Student Funding Formula" (specifically "Total Funding Formula Funds"). It directly affects school districts, charter schools, and the State Department of Education by clarifying how enrollment data and funding calculations are legally described in state code. The bill does not change how funding is calculated or distributed - only the terminology used in legal references. This is a procedural clarification bill, not a policy change, and it died in committee in February 2025.
