Threema UX v2 — QR available on demand

Replaces the previous attempt that had the QR rendering inline above the channel help text. That placement didn't work for you in practice because it wasn't visible when you actually wanted it.

What this does instead

1. "Show QR" link next to the channel title in the threema card — visible at all times, clickable any time you want the QR.

2. Auto-opens the modal the first time you focus the add-ID input on the page (so a new user adding their first ID sees it without needing to click "Show QR" themselves). Doesn't re-pop after dismissal — the link covers re-opens.

3. Modal with QR + 3-step instructions + "AIAGENT" label. Plain <img> (no next/image), closes on ESC / overlay click / × button.

The earlier threema-setup.tsx component file is removed — replaced by threema-qr-modal.tsx.

After redeploy, the threema card under Authorized Users shows:

threema    [Show QR]                              0 users
            ────────────────────
            <help text: 'Enter your own Threema ID...'>
            ────────────────────
            [ input: A8K2P3X7    ] [ Add ]
            ^^^ focusing this opens the QR modal the first time

Clicking "Show QR" or focusing the input → modal with QR + steps.
