Fix 3 bugs: equip crash, enchantment not processing, spire spell casting

Bug 1: EquipmentTab handleEquip was passing useCombatStore to equipItem()
which needs the crafting store (has equipmentInstances/equippedInstances).
Fixed by using useCraftingStore instead.

Bug 2: processCraftingTick() from crafting-slice.ts was never called in the
game tick loop. Added call in tick-logic.ts when currentAction is
'design'/'prepare'/'enchant'/'craft' so enchantment progress advances.

Bug 3: equipmentSpellStates was initialized as [] and never populated from
equipped items. Added logic in tick-logic.ts to build equipmentSpellStates
from active equipment spells when climbing (currentAction === 'climb').
