refactor: Decentralize data fetching and add axis initialization

Refactor data fetching architecture from centralized App state to
component-local data management for improved maintainability and
data freshness guarantees.

Changes:
- SettingsModal: Fetch config data on modal open
- RecipePanel: Fetch recipe list on panel open
- IOMonitorPage: Fetch IO list on page mount with real-time updates
- Remove unnecessary props drilling through component hierarchy
- Simplify App.tsx by removing centralized config/recipes state

New feature:
- Add InitializeModal for sequential axis initialization (X, Y, Z)
- Each axis initializes with 3-second staggered start
- Progress bar animation for each axis
- Auto-close on completion
