feat(api): consolidate user profile update endpoints

Add delete_user, reset_user_password, and update_user endpoints to replace
individual update operations. Update database schema to include deleted_at
column for soft deletion. Add DeleteUser, ResetUserPassword, and
UpdateUserAdmin queries. Update Querier with new methods for user management.
