Enjoy streamlined usage of relations in diagrams

In a comprehensive update, we've enhanced how dependencies and drill‑downs of relations are labeled, expanded, and visualized while aligning how you can interact with them in free draw and dataflow diagrams so that you can work with diagrams more efficiently and consistently. This is what has changed:

1. Expand relations from shape arrows: Hover or click the arrows next to a shape to pick and insert dependencies, even with filters. Before, this menu was only utilized for collapsed relations on application fact sheets. Relations inserted via the arrows keep their directional placement when being replaced; those added from the context menu still occupy the first free space (usually bottom left).

2. Filtered/detached indicators: Visual badges show whether a drill‑down is filtered or detached and whether dependencies are filtered. Click a drill‑down badge to open the filter modal. Existing interface‑expansion badges on data flow diagrams moved to the center of shapes to avoid overlap with the new indicators.

3. Relation labels on connectors: The new "Relation" option in the "Labels" menu allows you to show and hide the name of the related fact sheet type on all relations simultaneously.

4. Solid style of relations: Connectors representing relations are now rendered as solid lines with directional arrows and no longer dotted lines.

5. Automatic updates to relations: Like drill-downs, the dependencies now show updates from the inventory. You can still manually delete a dependency without changing inventory content, but it will appear missing in the updates. Consider using filters if you want to focus on a subset of fact sheets.

6. Label parity: Freedraw now supports multiple labels for collapsed interfaces and applies label changes to all shapes on the diagram, not only new shapes (same behavior as dataflow).
