[P2 Bug] Forewarn treats self status moves as 80bp

Describe the bug

Right now Forewarn treats StatusMoves as 1 base power correctly: https://github.com/pagefaultgames/pokerogue/blob/main/src/data/ability.ts#L2865

The issue arises because SelfStatusMoves extend Move rather than StatusMove so self status moves do not have their base power set to 1 but instead -1 which is then treated as 80 for Forewarn.

export class StatusMove extends Move {
  constructor(id: Moves, type: Type, accuracy: integer, pp: integer, chance: integer, priority: integer, generation: integer) {
    super(id, type, MoveCategory.STATUS, MoveTarget.NEAR_OTHER, -1, accuracy, pp, chance, priority, generation);
  }
}

export class SelfStatusMove extends Move {
  constructor(id: Moves, type: Type, accuracy: integer, pp: integer, chance: integer, priority: integer, generation: integer) {
    super(id, type, MoveCategory.STATUS, MoveTarget.USER, -1, accuracy, pp, chance, priority, generation);
  }
}

A bit of a refactor and as far as I can tell the only difference between SelfStatusMove and StatusMove is the MoveTarget but want to make sure that there will be no breaking changes.
