Improvements in User Management screen

[hrishavjha]

• The table has no pagination in the User Management screen. With more users coming in the screen will become weirdly scrollable.
  Suggested change: Provide pagination to the table to limit the number of users in each page. For reference look into ExperimentDashboardV2 files.
• The useUsersQuery API which is used in the User Management screen doesn't support pagination as well as filters, due to which the search is in FE only. For a large number of users this will create performance issues in FE.
  Suggested change: Add pagination and filters in the BE and update the controller in AccountSettingsUserManagement.
