A11y: group the captcha-type radio buttons on Global Settings

[vivi-the-going-merry]

What was broken

The recaptcha/hcaptcha/turnstile radio set on Formidable's Global Settings > Captcha tab had no programmatic grouping — assistive tech couldn't announce them as a related set (IBM Equal Access input_checkboxes_grouped, flagged by the Cypress a11y run in formidable-pro).

What changed

classes/views/frm-settings/captcha/captcha.php: added role="radiogroup" to the existing wrapper div, with aria-labelledby pointing at the existing "Select Captcha Type" heading (given a matching id). Markup-only — no fieldset/legend (would add unwanted browser chrome), no CSS or JS changes. Same pattern already used elsewhere in this codebase, e.g. classes/views/frm-fields/front-end/gdpr/gdpr-field.php.

How it was verified

Reproduced and confirmed locally via a disposable formidable-preview-env instance (Playground CLI) — before the fix, the rendered Global Settings page carried no role="radiogroup"/role="group" on this wrapper; after, role="radiogroup" appears exactly once with a correctly-resolving aria-labelledby reference, and the page's total line count is unchanged (no other markup/visual side effects). The repo's own cy.checkIbmAccessibility assertion is non-blocking in CI (assertCompliance(false), see formidable-forms#3356), so this couldn't be confirmed via a CI red/green signal.

Closes Strategy11/formidable-pro#6699
