BI-2964: Applied observation filtering and pagination on BrAPI side a…

[humsika]

Description

Story: BI-2964
Updated the observation GET flow so filtering by program and study, along with pagination, is performed by BrAPI instead of BI-API. BI-API now sends the requested page and page size to BrAPI and returns BrAPI’s pagination metadata while preserving the existing observation and trait-ID processing.

Dependencies

bi-web: epic/BI-2862
bi-api: feature/BI-2964
brapi-Java-ProdServer: feature/BI-2964

Testing

• Open Experiments & Observations and select an experiment containing observations.
• Verify that the observations load successfully.
• Apply filters and confirm the displayed observations match the selected filters.
• Navigate between different pages and confirm the correct data loads on each page without errors.
• Change the page size, if available, and confirm pagination continues to work correctly.

I am curious why this code existed in the previous implementation, but I am glad you kept the use case working. Should be fine for now unless someone wants something different.
