Prop 248: Decrease the minimum deposit amount for deployment and bid transactions

If successful, this parameter-change governance proposal will lower the minimum deposit for both deployment and bid create transactions from 5AKT (~$22) to 0.5AKT (~$2.20). This will decrease the cost of deposits on leases by 90% and reduce the upfront burden on tenants. In particular, this change will provide relief for tenants with low cost deployments.
