Story - Prologue is skipped

[Yentis]

The prologue chapter is skipped when a new account is created.
It also clears a bunch of stages in chapter 1 automatically

Expected behavior:

• Play the prologue on new account
• If prologue is skipped -> clear all prologue chapters
• Don't clear anything from chapter 1

Low priority, will fix when core systems are implemented.
