Revise board of regents laws to remove statutory requirement for student regent

This bill removes the legal requirement for a student regent position on Montana's Board of Regents, allowing the governor to appoint regular members to fill that seat instead. It amends state law to eliminate the statutory provision that reserved one seat specifically for a full-time student appointed by the governor, while keeping other appointment rules unchanged. The bill includes a transition plan where the governor appoints a regular member to serve a partial term starting July 1, 2025, followed by a full seven-year term beginning February 1, 2030. This change affects the composition of the Board of Regents by ending the guaranteed student representation that currently exists under Montana law.
