[FEATURE] Auto-adjust diagram zoom/pan to the participants involved in the current step

[QY-25123]

Feature

In the OAuth Debugger's sequence diagram, when the interaction moves between participants that are far apart (e.g. Step 5 switches from Client–MCP Server to Client–Authorization Server), the diagram view doesn't follow. Since the two participants sit far apart horizontally, the current pan/zoom only shows the empty space between them and misses the actual message content, as shown in the attached screenshot.

Solution

Automatically adjust zoom/pan (fit-to-view or center-and-zoom) to the two participants relevant to the currently active step whenever the step changes, so the interaction is always fully visible without manual scrolling/zooming.

Alternatives

• Keep manual zoom, but add a "Focus this step" action (distinct from the existing "Show in diagram") that recenters the view.
• Add a mini-map indicator showing which part of the diagram is off-screen.

Additional Context

Screenshot attached showing Step 5's interaction only partially visible in the diagram.
