Releases for Captcha Keypad

Keypad themes (issue #3576397)
Three built-in display themes give site builders control over how the keypad is rendered:

Plain — the original compact floating layout, unchanged from previous releases
Horizontal (new default) — larger touch-friendly buttons in a two-column grid with the code input on the left
Vertical (new) — 3×3 button grid with the code input at the top, suited to narrow sidebars and mobile layouts
The active theme is selected on the admin settings page (Admin → Configuration → System → Captcha Keypad).
