Refactor organization and user management components/tests for simplification and improved clarity

- Removed unused properties (`slug`, `is_active`, etc.) in organization and user-related components and test data.
- Simplified function data typing by removing redundant `any` usage.
- Updated `params` in `OrganizationMembersPage` for Promise resolution and async handling.
- Cleaned up unused variables and streamlined form handling in `AddMemberDialog`.
