Spokeflow partial settlement proposal

Review the independently proposed patch below, including its unchanged callers. A bike transfer has exactly one source and one destination. The source needs enough stock and the destination enough empty docks; cargo cycles have their own limit and electric support needs approval. Cargo transfers avoid the truck startup fee. Dashboard imbalance reduction compares both endpoints before and after each confirmed transfer. The settlement calculation and frontend metric both violate the contract. Preserve rounding, unit conversion, cancellation and repeated-plan behavior while repairing them. The repository includes a resource specification inspector, native database, booking timeline and server-derived insights. Run bash test/run.sh. Browser checks include mobile confirmation, durable reload, independent HTTP probes and regression safeguards.
