Cite every Wickr log, and read the Biome text session epoch from the evidence path

[abrignoni]

Two fixes.

• wickr_app_log named only the last log as its source, so a report drawing on several Wickr logs cited one and omitted the rest. It now lists every log it reads. Row counts are unchanged (120 on iphone11_ios17, drawn from 9 logs).
• biomeTextinputses chose the Unix or Cocoa epoch, and skipped tombstone files, by testing the absolute staged path. An output folder named "restricted" shifted every start time back 31 years. Both tests now read the evidence-relative path.
