172c1ad026cc38c6f52679e74c14579ecc77c48e test: expand LimitOrphan and EraseForPeer coverage (Greg Sanders)
28dbe218feef51cbc28051273334dd73ba4500c0 refactor: move orphanage constants to header file (Greg Sanders)

Pull request description:

  Inspired by refactorings in #30000 as the coverage appeared a bit sparse.

  Added some minimal border value testing, timeouts, and tightened existing assertions.
