[issue-527] fix: remove unused imports for collectAsState

All unused imports for `collectAsState` were successfully removed from the modified files in the codebase, ensuring compliance with the refactor that replaced `collectAsState` with `collectAsStateWithLifecycle`. The project was built successfully, and no errors were encountered during the process.
