feat: improve data export destination graph

[tgmendes]

Summary

• Group export routes by destination so shared collectors render once with converging connections.
• Make source and destination nodes clickable, and add a destination editor for names, OTLP endpoints, headers, and sensitive-data policy.
• Preserve stored write-only header values during edits and clarify the export-enabled helper text.
• Add focused coverage for grouping, node interactions, and destination editing.

Motivation

The export graph duplicated collectors when multiple data sources sent to the same destination. Destinations also had no direct editing path, which forced users to recreate configuration instead of maintaining the shared collector in place.

Summary by cubic

Groups export routes by destination so a shared collector renders once with converging connections, and makes source and destination nodes clickable with a new destination editor. Previously each route rendered its own destination node and destinations had no in-place editing path.

Details

• Tightens endpoint validation to reject query strings, fragments, userinfo, control characters, and non-HTTP(S) URLs.
• Validates header names as HTTP tokens and rejects control characters in header values.
• Clicking a source node opens the existing export configuration sheet.
• Clicking a destination node opens a new sheet for editing name, OTLP endpoint, headers, and sensitive-data policy.
• Write-only header values stay preserved on edit and are never displayed back in the form.
• The enable toggle helper text now says data starts exporting as soon as you save.
• Adds unit tests for destination grouping, node interactions, destination editing, and the new validation rules.

Running ultrareview automatically — This PR introduces a new destination editor with write-only header handling, grouping logic, and a large UI refactor. Bugs here could leak stored header values or corrupt destination configuration, warranting a deep multi-pass review.. I'll post findings when complete.

Demo

What it shows:

1. Multiple data sources converge on one shared destination node.
2. Clicking a source card opens its route configuration.
3. Clicking the destination card opens the shared destination editor; saving updates the graph.

Fictional sample data.
