refactor: Redesign Invoker disciplines for pact bonuses and guardian boons

- Replace generic spell-casting/void-manipulation with pact-focused disciplines
- Add Pact Attunement (light): reduces pact signing time, boosts pact affinity
- Add Guardian's Boon (dark): amplifies all guardian unique perks
- Add pactAffinityBonus and guardianBoonMultiplier stat keys to effect system
- Apply pactAffinityBonus in pact signing time calculation (gameStore)
- Scale guardian boon values by guardianBoonMultiplier (combat-utils)
- Guard Invoker discipline activation behind signedPacts.length > 0
- Add 'Signed guardian pact' prerequisite display in discipline-math
