Two bugs prevented form submission entirely: 1. `challengeurl` attribute was renamed to `challenge` in altcha v3 — the widget silently ignored the old name so it never fetched a challenge. 2. `altchaWidget.value` is not an exposed property on the v3 custom element; read the solved payload from the hidden `<input name="altcha">` the widget renders in light DOM instead. Also clears the err-altcha error message at the start of each submit attempt so it doesn't linger after the user completes verification and retries.
