feat: add "Open in IDE" integration for source files

[PhenX]

What & why

Adds a comprehensive "Open in IDE" feature that lets users click any source path in the dashboard to jump directly to that file in their local editor. This bridges the gap between the web dashboard and local development workflows.

The feature supports three methods:

• VS Code (and variants: Insiders, VSCodium, Cursor) via vscode:// URL scheme
• JetBrains via jetbrains:// URL scheme (requires JetBrains Toolbox)
• JetBrains local server via HTTP endpoint (requires IDE Remote Control plugin)

An "Auto" mode probes the JetBrains local server first (the only detectable method) and falls back to a URL scheme launch.

All preferences (method, workspace root, IDE product/port) are stored per-browser in localStorage — never sent to the server — since the source mapping is inherently per-device. Users configure these once in a settings modal accessible from any source path or the user menu.

Implementation details

• useOpenInIde composable: Manages preferences, resolves workspace roots (with per-project overrides for monorepos), and orchestrates the launch logic. Handles toast notifications for success/failure feedback.
• OpenInIdeLink component: A thin, reusable trigger that renders a source path with hover-revealed IDE controls (icon for default method, caret for chooser). Safe to drop into any component showing a file path.
• OpenInIdeSettingsModal component: Global settings UI for configuring method, workspace root, VS Code flavor, JetBrains product/port, and per-project overrides.
• ide-links utility: Pure URL builders for the three schemes, plus workspace-path joining. Kept free of Vue/DOM for unit testability.
• Shared parseLocation: Moved from server-only to shared/ so the browser, server, and demo router all parse file:line:col strings identically.

How was it tested?

• Added comprehensive unit tests for URL builders and path utilities (ide-links.test.ts)
• Existing parseLocation tests updated to import from shared location
• Manual integration: component wired into multiple pages (test runs, failure clusters, test cases, flaky tests) with project context threaded through for workspace-root resolution
• Settings modal mounted globally in default layout, accessible from user menu and any source path

Checklist

• PR title follows Conventional Commits (feat(...))
• Tests added for URL builders and path utilities
• Docs added (docs/ide-integration.md) with setup instructions and method comparison
• Help content added for the settings modal
• User-facing components integrated into existing pages (test runs, clusters, test cases, flaky tests)
