Add global interaction panel and bulk enable/disable interaction buttons

In the current Edit Interactions experience in Power BI Desktop, interaction settings are edited on a visual-by-visual basis. This becomes very time‑consuming when there are many visuals on a page, especially if some are overlapping or hidden.

Proposed improvements:

1. Add buttons to disable all interactions at once and to restore all interactions at once.

2. Add a global interaction panel where designers can see and edit all interaction relationships between visuals (source ↔ targets) in one place, without having to select each visual individually.

In summary, these improvements would save time and reduce complexity when designing reports in Power BI Desktop, providing a faster and easier way to manage interactions between visuals. This would make developing any dashboard much more efficient, allowing interaction settings to be edited, reviewed, and adjusted with ease, especially in reports with multiple visuals and complex layouts.
