Subject: [PATCH] Fix #26492: Drag tool shows per tile error when running out
 of money midway (#26493)

The path and wall drag tools query each tile individually for affordability so all queries pass when the player can afford any single tile. But if the total exceeds available funds, execution fails midway with per tile error windows. To fix it this adds a total cost check against available funds after the query phase, showing a single combined error with the full cost before execution actually starts
