refactor: remove unused Pinia stores and related code

- Deleted the layout-store, profiles-store, and index.ts files from the Pinia store setup.
- Removed the zod-sync script as it is no longer needed.
- Cleaned up the tsconfig.json file by removing unnecessary references.
- Updated the login logic in the profiles package to use polling for login results instead of in-process waiters.
- Added validation methods for personal data and profile parameters.
- Introduced new tests for validation logic in profiles and registration packages.
- Enhanced email normalization and validation in the registration package.
