Privacy Friendly Captcha - Event Registration

This module extends the event registration process on your Odoo website with an ALTCHA captcha, a privacy-friendly alternative to other captcha services.

When a visitor opens the event registration form, an ALTCHA widget is placed in the form's footer area. The main submit button stays disabled until the visitor has successfully verified the captcha. As soon as the captcha state changes to verified, the button becomes clickable; if the verification is lost or not completed, the button is disabled again.

The same protection is applied to the ticket details step: whenever the visitor changes ticket quantities, the module re-checks the captcha state and disables the submit button if verification is missing.

Because the module installs automatically together with its dependencies, no manual configuration is needed. It only affects the frontend event registration screens and does not add any new menus, database models or reports. It relies on the existing website event registration and the generic ALTCHA website functionality.
