feat: add attunement leveling system, debug tab, and UI improvements

- Add mana pools display to ManaDisplay component with collapsible elements
- Add Debug tab with reset game, mana debug, time control, attunement unlock, element unlock
- Remove ComboMeter from UI (header and SpireTab)
- Remove 'scrollCrafting' capability from Enchanter attunement
- Add attunement level scaling (exponential with level)
- Add XP progress bar and level display in AttunementsTab
- Add getAttunementConversionRate and getAttunementXPForLevel functions
- MAX_ATTUNEMENT_LEVEL = 10 with 3^level XP scaling
