Replaces ambiguous shorthand references like `event` and `user` with more descriptive names such as `event_crud` and `user_crud`. Updates imports, function calls, tests, and other references across the codebase to maintain consistency. This improves code readability and reduces potential confusion.
Introduce methods to count user, public, and upcoming events to enhance CRUD functionality for events. Additionally, add a `PaginatedResponse` schema to simplify and standardize paginated API responses. These updates support improved data querying and response handling.
This commit introduces a new CRUDEvent class to manage event-related database operations, including retrieval, creation, updating, and deletion of events. It includes corresponding unit tests to ensure the correctness of these functionalities, updates event schemas for enhanced validation, and refines timezone handling for event dates and deadlines.
