InitiateBridgeTransfer is the canonical user-tx admission point on B-Chain — it drives MPC signing capacity. Add a Fee uint64 field to BridgeMessage and attach a FlatPolicy at MinTxFeeFloor in Initialize. The fee gate refuses zero-fee transfers before any MPC signing capacity is consumed. Consensus-internal callers bypass via pendingBridges / bridgeSigner direct access.
