chore(madmin): remove dead trace structs, keep TraceType bitflag helper only TraceInfo, TraceInfoLegacy, TraceHTTPStats, TraceCallStats, TraceRequestInfo, TraceResponseInfo, StorageStats, and OSStats are unreferenced outside trace.rs. Trim to TraceType + its bitflag operations which are actively used by service_commands.rs and profile_admin.rs. -139 lines (215 -> 76 lines)
