feat: Refactor API services and UI components

This commit refactors the API service to use a consistent `fetch` wrapper for all requests, improving error handling and authorization logic. It also updates UI components to reflect changes in API endpoints and data structures, particularly around notifications and extraordinary expenses. Docker configurations are removed as they are no longer relevant for this stage of development.
