Track WAL archiving lag by comparing current WAL position to last archived segment position, providing visibility into archival delays. This works well with planetscale/hzdb-operator#1052 - we can/should expose this metric on single node branches I think, and then users can think about these cases themselves correctly and see e.g. historical spikes etc.
