docs: correct the places where documents contradicted their own evidence

An independent audit found ten documents printing values their evidence files do not contain. C-1 printed a session count of 0 where the evidence says 4, C-2 printed a success readback for a command that exited 1, and A-1 credited the conntrack flush with a split that the timestamps attribute to a pod restart four seconds earlier.

Also measured wal_writer_delay, which A-3 had asserted as matching without ever querying it, relabelled the A-6 control that moved 41 percent, noted A-8's nine-sample resolution, corrected D-1's RTO to the 41 seconds its own timeline shows, and added a correction banner to D-2. Every experiment document now links its evidence files with their real collection times, and the duplicate screenshots are documented as duplicates.
