[UEPR-523] Update Share Modal Flow

[adzhindzhi]

Resolves

• UEPR-523

Proposed Changes

• Wait for project to be shared in Project Watcher before moving to www

Reason for Changes

• Now that the manual thumbnail update is moved to the editor, we want to display the Share Modal inside the editor and move to www after the project was actually shared

Test Coverage

Existing tests complete successfully; no new test cases added

Pull request overview

Updates the editor’s Share/Community transition behavior so navigation to the project page can be delayed until the project has completed relevant background operations (saving and, for Share, sharing), aligning with the updated share modal flow in UEPR-523.

Changes:

• Extends ProjectWatcher to track both “saving” and “sharing” wait conditions.
• Updates MenuBar to pass structured wait conditions into ProjectWatcher and to provide isShared for the Share flow.
