Revise legislator compensation during interim

This bill revises Montana legislators' compensation and expense rules when the legislature is not in session, directly affecting state legislators attending interim meetings. It establishes distance-based pay tiers: for meetings within 100 miles, legislators receive one day's pay plus basic meal and mileage; for 100-400 miles, two days' pay plus additional meals and lodging; and for 400+ miles, three days' pay plus full meals and lodging. Remote participation earns one day's pay per 24-hour period. The bill clarifies that legislators cannot be compensated for time spent beyond authorized interim business.
