refactor(App): streamline repo search and row mapping functions

This update enhances the repo search functionality by passing the search term directly to the filtering functions. It also refactors the row mapping functions to accept parameters for better flexibility and clarity, improving the overall readability and maintainability of the code.

- Simplified search and mapping logic for repositories
- Improved parameter handling in helper functions
