Cannot set lightning redirect

[ibz]

Describe the bug

Trying to set a lightning redirect results an error: Error updating Lightning address: Authorization header not found

To Reproduce
Steps to reproduce the behavior:

1. Go to Settings
2. Check "LN redirect"
3. Set an address
4. Click "Save"
5. An error occurs

Additional context

Upon investigation, it seems that updateLightningAddress in lightningaddress.ts expects the Authorization header to be there, but updateLnRedirect in userSettings.ejs never sets the header.
