Improve Initialization of Validators with a Single ED25519 Reward Address and Enhanced GUI Features

[Ja7ad]

Description

The current implementation generates validators with individual reward addresses during the initial setup of a blockchain node. To optimize this process, we propose an improvement where a single ED25519 reward address is used for all validators during initialization, while maintaining flexibility for the number of validators. This update will include modifications to the node setup process, improvements to the reward address handling, and changes to the GUI for better clarity and control over validator visibility.
