Modular Transport Streets (Simple, Scalable Transport Backbone)

Add Transport Streets as a modular transport system similar to rails.
-Place once, drag to extend
-No capacity by default
-Capacity is added via modules (pipe, flat conveyor, loose conveyor)
Transport Streets can be connected. After connecting, players can:
-assign filters (items or fluids)
-set transport directions
-change routing without rebuilding
Higher tiers allow more modules and higher throughput, with higher cost and maintenance.
This reduces conveyor and pipe spaghetti, scales better into late game, and keeps logistics planning intact.
