refactor: eliminate as any type casts across 18 source files

- Fix computeDisciplineEffects() to not require GameState parameter
- Fix getUnifiedEffects() to accept proper partial state type
- Replace upgradeEffects as any with proper UnifiedEffects type
- Replace explicit : any annotations with proper types (ComputedEffects, DesignProgress, SpellDef, etc.)
- Fix activity-log.ts eventType casting
- Fix crafting-design.ts computedEffects and designProgress types
- Fix page.tsx grimoire spell rendering with proper SpellDef property names
- Fix StatsTab ManaStatsSection with proper ManaStatsEffects interface
- Remove unused imports (useDisciplineStore from page.tsx, LeftPanel.tsx)

Remaining: 1 as any in craftingStore.ts (pre-existing CraftingStore/GameState architectural mismatch)
