Uses static property for manager ID

Refactors to use a static property for the OpenTalent manager ID.

This change improves code readability and maintainability by
centralizing the manager ID in a static property of the
`WebsiteListMenuBuilder` class. This avoids accessing it via
runtime config and makes the code more self-documenting.
