Subject: [PATCH] fix(qr): lock QR code modules to black-on-white across all
 themes

AntD's <a-qrcode> defaults the module color to the active theme's
text token. Under the dark and ultra-dark themes that text is a light
gray, so the QR rendered low-contrast on the white canvas background
and phones could not lock onto it. Pinned color="#000000" and
bg-color="#ffffff" on every <a-qrcode> usage (share links in
QrPanel, 2FA enrollment in TwoFactorModal, sub/json/clash codes on
SubPage) so the contrast stays high regardless of panel theme.
