CIP-0119 approved: free 90-day transfer-preapproval base duration

Canton Foundation CIP repository (approved 2026-06-15): CIP-0119 adds transferPreapprovalBaseDuration (default 90 days) to AmuletConfig—creating or renewing preapprovals within that window is free beyond standard traffic (including free base traffic), addressing exchange onboarding after CIP-0096 removed validator liveness rewards.
