[BUG] Browser panel URL bar strips https:// when copying or editing the URL, breaking navigation

What's Wrong?

The browser panel normalizes URLs inconsistently. When I paste google.com, it automatically adds https:// internally and displays www.google.com/ in the URL bar. When I paste https://localhost:44308/, the page loads correctly and the URL bar shows localhost:44308/ (the https:// is hidden). However, if I then copy the URL or edit it, the URL bar uses the version without https://, and the page fails to load because localhost:44308/ alone is treated as an invalid/different address.

What Should Happen?

When copying the URL, it should copy the real, fully-qualified URL (including the https:// scheme actually being used internally), not the display-only stripped version.
When editing the URL, the URL bar should show the actual scheme (https://) being used, so editing doesn't accidentally drop it and break navigation.

Error Messages/Logs

No explicit error message is shown; the page simply fails to load after copying/editing the URL because the scheme (https://) is missing from the resulting address.

Steps to Reproduce

1. Open the browser panel in Claude Code.
2. Enter https://localhost:44308/ in the URL bar. The page loads correctly, and the URL bar displays localhost:44308/.
3. Copy the URL from the URL bar (or click into it to edit it).
4. Notice the copied/edited value is localhost:44308/, without https://.
5. Paste/submit that value again (e.g., in a new tab or after editing) — the page fails to load because the scheme is missing.

Note: as a comparison, pasting google.com (no scheme) correctly gets https:// added internally and resolves to www.google.com/, but this internal scheme is not reflected/preserved when copying or editing.

Additional Information

The issue specifically affects local development URLs (e.g., localhost with a custom port and https), which is a common workflow when debugging locally running sites in IIS/ASP.NET.
