fix: remaining tab migrations to modular stores

- CraftingProgress, ManaDisplay, TimeDisplay: fmt/fmtDec imports → @/lib/game/stores
- SkillsTab, SkillRow, SkillUpgradeDialog: imports → @/lib/game/stores
- StatsTab and sub-components: fmt/fmtDec imports → @/lib/game/stores
- CategorySkillsList: GameStore type import → GameCoordinatorStore
- EnchantmentDesigner types/utils: GameStore type imports → GameCoordinatorStore
- Header: fmt import → @/lib/game/stores

Moves remaining non-hook usage files from legacy @/lib/game/store to modular @/lib/game/stores
