patch

Consolidate ExperimentSessionStore resolution onto TaskStore.getExperimentSessionStore() across the dashboard experiment routes, CLI experiment finalize command, and pi-extension tool. Removes the temporary FN-4218 fallback shim introduced in FN-4222. Behavior unchanged; single canonical store-resolution path.
