Fix: Add scrolling to Node Management window (#12746)

[mmlado]

What does the PR do

The Node Management screen lacked vertical scrollability when the window was resized, causing content to become inaccessible.

This wraps the entire layout in a StatusScrollView to enable scrolling when content exceeds the visible area.

Fixes #12746

Affected areas

Node layout

Architecture compliance

• I am familiar with the application architecture and agreed good practices.
  My PR is consistent with this document: QML Architecture Guidelines

Screencapture of the functionality

Impact on end user

Before: If the window was small, the user didn't see all the fields
After: If the window is small, the user can scroll to other fields.

How to test

1. Select Node Management in the left pane.
2. Resize the window such that its vertical dimension is low.
3. Scroll

Risk

Cosmetic changes. Minimal risk.

Not sure about this... I think what should be scrollable is the "Logs" section (or even the inpput field, in case it's multiline), but not the whole view

The current issue is the bottom content can't be seen. The first two columns are fixed at 300 height, so there is no space left. Would it be better for the mailserver interactions and logs fields to resize based on the window size?

Yes, definitely (it can be a ratio, like 1/3); nothing should be hardcoded like this
