This fix ensures image size options passed through website URLs are handled correctly, so images can be resized as intended. It improves reliability for image display across website, profile, and e-learning pages without changing how users interact with the system.

Before this commit it was impossible to pass those parameters in the URL because
they were received as string but expected as int.

Goal records in Gamification now show a readable name instead of an unclear technical label. This makes it easier for users to identify and understand goals in the interface, such as seeing “Goal / Set your Company Data.”

Description of the issue/feature this PR addresses: Create a human readable and clear title for goal records.

Current behavior before PR: There is no valid `_rec_name` set on the model `gamification.goal`, resulting in an ugly title:

Desired behavior after PR is merged:
There is a clean goal title. In this example "Goal / Set your Company Data"
