Clean up existing boss content, part 1 (V3 Milestone 5)

From the two-wiki review (Fextralife and Fandom):
- True Corrupted Monk: phase 2 keeps every phase-1 move alongside the
  illusion summoning; the illusion text no longer gives a shadow count
  or the misleading Bite Down tip, and adds the tree aerial-Deathblow
- Guardian Ape: add the phase-2 Jumping Sweep from the Fextralife
  attack table; the rolling body slam can be blocked
- Owl (Father): Shadowfall is the Mushin combat art 秘传·巨型忍者落杀
  (both wikis say so); the firecracker dodge mistake moves to the
  5-slash firecracker combo where the source puts it
- Isshin: deflecting Ichimonji Double leads into a force-wave follow-up
