tracing: surface TraceLeiosDb via the Leios kernel tracer
Adapts cardano-node to the updated ouroboros-consensus newLeiosDBSQLite signature (Tracer IO TraceLeiosDb -> FilePath -> ...) from IntersectMBO/ouroboros-consensus#2062 by contramapping the TraceLeiosDb constructor into the existing Consensus.LeiosKernel tracer. SQLite UNIQUE/PRIMARY KEY collision events are given Warning severity so they remain visible under the default Notice configuration. Co-Authored-By: Claude Fable 5 <[email protected]>
