Fix #10624 - Prevent Multiple Submissions on Survey Forms

[SinergiaCRM]

Description

As described in #10624 , survey response forms allowed multiple identical submissions when users repeatedly clicked the "submit" button before the usual redirection occurred.

This issue has been resolved by modifying the survey response form code. The "submit" button is now disabled upon the first activation (submission) to prevent additional clicks.

Motivation and Context

This change is required to ensure data integrity and avoid multiple identical responses from a single user. By disabling the "submit" button immediately after submission, it eliminates the possibility of repeated actions before redirection, improving the reliability of survey results.

How To Test This

1. Create a survey and make it public.
2. Access the survey link, respond to the survey, and try pressing the "submit" button repeatedly.
3. Verify that it is no longer possible to press the "submit" button multiple times.
4. Check the CRM to ensure that only the correct (single) response has been recorded and that no duplicate responses appear.
