Industry Manager

Adds an Industries button to the game bar that opens a manager window: status, output per year, stock levels, nearest town, search and filters, bulk keep-open and closing alerts. Each industry opens its own window with the game's production and cargo flow cards, productivity boosters, serving lines with capacity / utilization / frequency / rate / balance, cargo on the road, supply chain, station tabs, and nearby partners with one-click line creation and optional auto-buy trucks. Per line: add or remove trucks, optional auto-scale, and a Problems filter plus profit column in the list.
