MAB-607 Section B bulk upload frozen

[ronnyReliefapp]

Description

This PR fixes the UI freezing issue when performing bulk uploads of fauna or flora lists in Nomination form Section B. The previous implementation added rows one by one, triggering multiple synchronous re-renders that blocked the main thread. The new implementation uses bulk value assignment, which triggers only a single re-render, significantly improving performance and responsiveness.

@ronnyCapriles
It's better, it doesn't freeze when uploading, but it seems the system is super slow once the rows are uploaded
Maybe you can also check if anything can be done to improve that
