Surface BitLogin sign-in rejections instead of silently swallowing them

devLogger.warn is a no-op outside dev mode (IS_DEV_MODE = false on
this deployment), so when AuthService.requestLogin() rejected a
BitLogin sign-in -- e.g. the invite-only access-control check
("Access restricted to admins and moderators users only.") -- nothing
ever told the user why. The widget itself doesn't know bitvid rejected
it, so it kept showing its own "Signed in" screen, and the login modal
never closed, looking exactly like a hung/broken close button.

On rejection: route the error through app.handleLoginModalError (the
same visible-banner path every other sign-in method already uses) and
reset the widget via widget.logout() so it doesn't keep claiming a
session bitvid never actually granted.

Also added a WeakSet guard so wireBitloginLogin() can never attach two
"bitlogin-login" listeners to the same element, regardless of how
attachWidget() ends up getting invoked -- cheap insurance, no observed
bug currently triggers it.
