Feature Request: Add "Copy localhost URL" option instead of auto-opening browser

[brchn6]

Feature Request

Summary

Add an option to copy the generated localhost URL to the clipboard,
rather than automatically opening it in a browser.

Motivation

Currently, the extension opens the print preview in a browser automatically
without user control over which browser is used. A "Copy URL" option would
allow users to paste the localhost URL into any browser of their choice.

Proposed Behavior

• Add a button or setting: "Copy localhost URL to clipboard"
• The URL (e.g. http://localhost:PORT/...) is copied instead of auto-launched
• User can then paste it into their preferred browser manually

Benefits

• More user control over which browser handles the preview
• Avoids unintended behavior with default browser settings
