Fix isolation close by correction when using LRT objects in LLP1

Instead of separately scheduling the CBC for standard and LRT objects, the merged lepton containers should be supplied to the correction tool. The decors for this are then separately suffixed to create this distinction, which was the original reason why this was made distinct in the first place in !76968 (merged).

cc @schaffer to check the implementation and @ssnyder to check that I am not (re-)introducing any clashes with PHYS. cc @ewoodwar to try out the change with a test file and running it through the analysis code with the new suffix.
