fix: resolve all Priority 5 CRASH/BLOCKER issues (#51-#57)

- #51: Fix broken import path @/types/disciplines → @/lib/game/types/disciplines
- #52: Fix canProceedDiscipline() called with wrong arguments in discipline-slice.ts
- #53: Add local useState for activeAttunement tab filtering in DisciplinesTab
- #54: Make canProceedDiscipline() defensive when gameState is undefined
- #57: Remove stale CraftingTab export from game/index.ts
- Refactored DisciplineCard to use Zustand selector subscriptions properly
- Added DisciplinePerk type import to discipline-math.ts
