fix(core): improve User Management filtering and scope support

- Updated load_ae_obj_li__user to use search_ae_obj_v3 for complex account OR global filtering.
- Fixed zero-results issue by defaulting to 'All' scope (Current Account + Global).
- Added visual 'Account' vs 'Global' badges to user cards.
- Added 'Scope' selector to User Management page.
