Issue Summary

Work Tree: The user can see all existing releases and work items (without team membership) on Strategy and Product levels

Preconditions:
User#1 - non-Super Admin role, e.g. Product Owner.
User#1 should be a member of Portfolio#1 > Program#1 > Release#1 hierarchy
User#1 should have access to the Work Tree page on Enterprise and Product levels

Steps to Reproduce

FOR ENTERPRISE MENU

1. Navigate to the Work Tree page under Enterprise level > Leave side menu Release dropdown empty
2. Open in-page release filter > On this step User#1 can see all the Releases that exist on the platform > Select any Release except for Release#1
3. On the in-page Snapshots filter select a strategic snapshot that matches release selected in the previous step

FOR PRODUCT MENU

1. Navigate to the Work Tree page under Product level > Leave side menu Release dropdown empty
2. Open in-page release filter > on this step User#1 can see all the Releases that exist on the platform > select any Release except for Release#1
