Fix infinite hydration loop and stabilize global store synchronization

- Refactored layouts to derive account data from stable props instead of reactive stores.
- Wrapped store updates in untrack() with deep equality guards to prevent infinite re-renders.
- Resolved duplicate untrack declarations and missing imports across the project.
- Added fetch safeguards to Element_data_store to prevent redundant API calls.
- Standardized hydration patterns to break circular dependencies during initial load.
