interop: supervisor <> op-node mode renaming

[tynes]

This ticket represents the renaming of the supervisor <> node mode renaming per here. The previous names consistently confused people and the new names exist to make it easier to understand what is going on. All mentions of managed mode should be replaced with indexing mode

[protolambda]

All mentions of standard mode should be replaced with indexing mode

Rename managed mode to indexing mode #16385

Speaking of confusion; small mix up there
