[Feature Request]: Cleanup code specification in longitudinal app so it does not show all data-processing code on a Show Code button but it brings the code needed only for a specific module

[m7pr]

Feature description

Similarly to insightsengineering/teal.code#126 (comment) looks like code specification in longitudinal app is very limitied in specs, hence this shows the whole code of data processing when you click Show Code anywhere in any module in the app. I reckon this could be limited to just specific datasets.

Based on the discussion, the reason for code repetition is our use of the #>code and <code technique, which can be found here: https://insightsengineering.github.io/teal/latest-tag/articles/preprocessing-data.html#usage-in-teal-apps.

The drawback of this approach is that users will encounter repeated code in every module, as previously mentioned.

To mitigate this, we considered passing the code argument in the cdisc_dataset(code=) function. However, this would make the app.R file excessively long and potentially difficult to comprehend for new users looking at the gallery.

The team has decided to maintain the current approach for the time being.
Closing.
