Enhance the DevIndex controls by renaming tabs for clarity and exposing buffer settings for performance tuning.

1. Rename Tabs:
   • "Filters" -> "Search"
   • "Selection" -> "Settings"
2. Move Controls:
   • Move "Show Animations" CheckBox from "Search" to "Settings".
3. Add Buffer Settings:
   • Add "Buffer Row Range" ComboBox to "Settings".
   • Add "Buffer Column Range" ComboBox to "Settings".
4. Implement Logic:
   • Add onBufferRowRangeChange and onBufferColumnRangeChange to MainContainerController to update grid.body.

These settings allow users to tune the rendering buffer (the number of rows/columns rendered off-screen) for smoother scrolling.
