refactor: standardize filter handling across controllers

- Replaced "conditions" parameter with "filter" in various controller methods to unify the filtering approach.
- Updated related functions to utilize the new filter parameter, enhancing consistency in query handling.
- Improved overall code readability and maintainability by aligning naming conventions and refactoring filter-related logic.
