remove function call from package using `::` for fully imported packages

### Feature description

Based on the conversation https://github.com/insightsengineering/teal.modules.hermes/pull/336#discussion_r1348152030, it has been observed that there is a package-wide usage of the `::` namespace call for function from the *fully* imported packages.

**Acceptance Criteria:**
To meet the acceptance criteria, we need to remove these namespace references (from packages that are fully imported) and ensure that everything functions as expected.
