[Due for payment 2026-04-30] [Domain Control] [Release 4] [FE] Clean up domain adminship in App

[mountiny]

Part of #76750

Description

Clean up the legacy domain adminship handling in the App by removing the sharedNVP_private_admin_access_<domainAccountID> key and consolidating all domain admin information under the new domain_<domainAccountID> key.

Implementation Details

From the design doc:

Current State

Currently, users who are admins on the domain get the sharedNVP_private_admin_access_ key that indicates they are admins on the domain.

Required Changes

• As part of this project, we are consolidating all domain admin information under the domain_<domainAccountID> key
• The current data is duplicated in the app between the two keys
• Remove the sharedNVP_private_admin_access_<domainAccountID> key usage
• Update all references in the App to use the information from domain_<domainAccountID> instead
