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.
Renamed `event_theme` and `test_user_schema` file paths and imports to follow consistent plural naming conventions. This improves code clarity and aligns file and import naming across the project.
Introduced CRUD implementation, schema definitions, and tests for EventTheme. This allows creation, retrieval, updating, deletion, and querying of active event themes. Comprehensive tests ensure functionality works as intended, including edge cases for nonexistent themes.
