Multi-User 1-Click Login Selection

Current Issue: MainWP's 1-click passwordless login feature currently only logs users in with the administrator credentials that were used to establish the initial site connection. All team members using the 1-click login are logged in as the same administrator account, regardless of who is accessing the site.

Requested Feature: Add the ability to select different user identities when using the 1-click login feature from the MainWP Dashboard. This would allow team members to choose which user account they want to log in as on each child site, similar to the functionality provided by Glow.

Benefits: This would enable proper user accountability, individual access tracking, and allow team members to work under their own user credentials while still maintaining the convenience of 1-click access through the MainWP Dashboard.
