Refactor: Introduce LessonUiUtils to simplify lesson UI setup

MihaiCristianCondrea · MihaiCristianCondrea · commit 0dc6b9850bc4 · 2025-10-09T01:52:08.000+03:00
This commit introduces a new `LessonUiUtils` class to centralize and simplify the setup of the description section in various lesson activities.

Key changes include:
- A new `setupDescriptionSection` method in `LessonUiUtils` that handles setting the description text, header, layout preview header, and loading the banner ad.
- Refactoring multiple lesson activities (`LinearLayoutActivity`, `ChronometerActivity`, `ImageButtonsActivity`, etc.) to use the new utility method, reducing repetitive code.
- Minor code cleanup, including import reordering in several files.
