Fix internal settings generation

[dmytrotkk]

This pull request updates the node initialization and update workflows to ensure that internal settings are saved consistently when initializing or updating a node. The main change is to move the call to save_internal_settings from a lower-level operation to the higher-level CLI commands, ensuring settings are saved at the appropriate stage.

Improvements to node initialization and update workflows:

• The save_internal_settings function is now called at the start of both the init and update functions in node_cli/core/node.py, ensuring internal settings are saved before further configuration steps. [1] [2]
• The redundant call to save_internal_settings in node_cli/operations/base.py has been removed, centralizing responsibility for saving internal settings in the CLI layer.

Imports and dependencies:

• The import of save_internal_settings has been added to node_cli/core/node.py to support the above changes.
