BuildingPlotTimeoutCalculator

Calculates proportional timeout values for building plot operations. The previous fixed 3-second timeout was causing premature "Building TIMEOUT" notifications for properties with multiple buildings. This calculator scales the timeout based on the number of buildings to plot:

• 1-3 buildings: 10 seconds
• 4-10 buildings: 30 seconds
• 10+ buildings: 60 seconds

A minimum of 0 buildings still gets the smallest tier (10 seconds) to act as a safety net.
