Makes the Omen coupon only trigger bad luck once, like it used to (#81814)

## Why It's Good For The Game
Idk when it happened, but someone managed to not input an
`incidents_left` for the coupon's component addition, which made it
default to `INFINITE`. As such, this would actually leave you with a
**_worse_** curse than the quirk itself, since EVERYTHING would be more
likely to hit you.
## Changelog
🆑 Wallem
fix: The cursed coupon now only triggers a cursed event once, rather
than infinite times.
