File-Level Changes

Change	Details	Files
Remove handling of explicit minimum height messages and rely on existing applet container layout logic.	Delete processing of Dock::MSG_SET_APPLET_MIN_HEIGHT messages in NetworkPlugin::message. Stop calling setMinHeight on m_dockContentWidget based on external messages.	dock-network-plugin/networkplugin.cpp
Tighten the dock content widget layout to eliminate extra vertical spacing between the network view and action buttons.	Keep a fixed top margin on the main layout but explicitly set layout spacing to 0. Remove stretch and extra spacing previously added between the network view and the button row, so the content and buttons pack together without unintended gaps.	dock-network-plugin/dockcontentwidget.h

Hey - I've left some high level feedback:

• Removing the MSG_SET_APPLET_MIN_HEIGHT handling means any min-height commands from the dock will now be ignored; please confirm this message is no longer used or that the behavior change is intentional across all consumers.
• With the stretch and spacing removed, the bottom button widget may no longer stay visually anchored at the bottom when the container grows; consider using a spacer with adjustable size or layout alignment that preserves the bottom positioning without reintroducing excessive gaps.
