Spells: Pacify duration incorrect for timeline

[Telin]

Pacify and other lull spells in our era should have unique resist modifiers that scale with the mob's level. These modifiers are currently not implemented on P99, which affects the intended usefulness of these spells.

The current version behaves more like the Luclin/PoP era, where the duration was reduced to 42 seconds. However, in our era, the duration should technically extend up to 7 minutes. As a compromise, until the resist calculations are corrected to match the classic mechanics, I will set the max duration to half of the original—3.5 minutes.
