- service: drop groupRepo nil guard (DI must inject), switch SupportedModels to SliceStable to match doc - frontend: reuse user-side DTO types in SupportedModelChip/AvailableChannelsTable instead of duplicating shapes; narrow admin statusLabel param to ChannelStatus - tests: replace nil-groupRepo case with ListAll/ListActive error propagation and BillingModelSource default-backfill coverage
