fix(devices): pairing input moves into the Add Device modal

The pairing field sat at the bottom of the Devices page, below the
device grid — unreachable on any account with more than a screenful of
devices (the user's dev account has ~480 accumulated test devices;
scrolling 224k px to reach the field is a non-starter). The Add Device
button at the top of the page is where pairing intent already lives,
so the code input and Find device button now sit inside the Connect a
KOReader Device modal as instruction step 6, with the confirm card
swapping into the same modal (container keeps the pairing-lookup ids;
the htmx error-toast listener scopes to #add-device-modal now).

Verified live: modal renders the full instruction list + input, a
wrong code swaps the templ error partial inside the modal, and claim
still HX-Refreshes on success (modal state resets with the reload,
paired device appears in the grid).
