feat: source selection modal for connection import (XTB vs PPTB)

[Copilot]

Replaces the combined file picker + format auto-detection with an explicit source selection modal before the file picker opens. Resolves user confusion around importing XrmToolBox connections.

Changes

• New modal (src/renderer/modals/importConnectionSource/)

  • Two selectable cards: XrmToolBox (restricts picker to .xml) and Power Platform ToolBox (restricts picker to .json)
  • XTB card selected by default; selecting it reveals an inline hint panel with step-by-step XTB export instructions and the default ConnectionsList.xml path
  • Follows existing controller/view modal pattern (channel-based messaging via modalBridge)

• connectionManagement.ts

  • importConnections() now opens the source modal first, then opens a format-restricted file picker — no more .xml/.json auto-detection heuristic
  • Wired using the same promise-handler pattern as selectConnection and editConnection modals

• Use a meaningful title for the pull request.

• Follow the guidelines from the CONTRIBUTING.md.

• Test the change in your own code. (Compile and run)

• Resolve all GH Copilot comments.

Pull request overview

Adds an explicit “import source” selection step before the connection import file picker, to remove ambiguity between XrmToolBox (XML) and Power Platform ToolBox (JSON) imports in the renderer connection management flow.

Changes:

• Introduced a new BrowserWindow modal (controller + view) to select import source (XTB vs PPTB) and show XTB export guidance.
• Updated importConnections() to open the source selection modal first, then open a format-restricted file picker and parse accordingly.
• Added modal wiring (channels + promise handlers) in connectionManagement.ts using the existing modalBridge pattern.
