refactor: update theme and payment providers

- Renamed and reorganized the ActiveThemeProvider and PaymentProvider components for better clarity and structure.
- Introduced the ActiveThemeProvider component to manage the active theme and set cookies accordingly.
- Implemented the PaymentProvider component to initialize payment state based on the user's session.
- Updated imports in related components to reflect the new file structure.
