Impossible to handle blocked targets when flagging took place in another part of the organization

[richardolsson]

Description

A caller can flag a target using a feature called "Organizer Action Needed" (OAN). When that happens, the target is blocked from calling. This block is enacted in the entire organization tree, not just the specific organization where the call took place. But the UI to handle blocked callers does not understand this, so there is no way of handling a flag that took place in another organization.

This is probably limited by lack of functionality on the backend.

Steps to reproduce

1. While making calls in a sub-organization (e.g. org 2), flag a target
2. Go to https://app.dev.zetkin.org/organize/1/projects
3. Go to any call assignment and make sure it's targeted
4. In the blocked section, there should be at least one who is flagged. Click the "View list" button next to it.
5. Inspect the list that opens

Expected Behaviour

The list should contain anyone who's blocked, and the "Flagged calls" column should contain a exclamation point for anyone who's still blocked.

Actual Behaviour

The list contains all who are blocked, but the "Flagged calls" column is empty for people who are blocked due to flagged calls in the sub-organization.
