Look up "index field" in display cycles
Again, to make epoch indexing a flip-of-switch for testing look up the `Viz.index_field: str` value when updating labels. Also, drops the legacy tick-type set tracking which we no longer use thanks to the new throttler subsys and it's framing msgs.pre_viz_calls
