fix: BarWidget QML errors preventing plugins from loading in Noctalia

[VictorGSchneider]

Root cause

Both stoa-doctor-pill and stoa-drive-pill BarWidget.qml files had two issues that caused Noctalia to fail loading them — so they never appeared in the Bar Widgets dropdown:

1. NToolTip was removed from Noctalia's widget library — the correct pattern is to declare a tooltipText string property on the root item instead. Using NToolTip caused a QML type-not-found error at load time.

2. Missing required BarWidget contract properties — Noctalia's PluginBarWidgetSlot injects screen, widgetId, section, and sectionWidgetIndex at runtime. Without these declared on the root item, Noctalia may reject the component.

Changes

• Replaced NToolTip { target: root; text: ... } with property string tooltipText: ... on root item in both BarWidget.qml files
• Added missing required properties to both BarWidget.qml files:

  property ShellScreen screen
  property string widgetId: ""
  property string section: ""
  property int    sectionWidgetIndex: -1

Test plan

• git pull && ./install.sh (symlinks already exist — no-op)
• Restart Noctalia (qs -c noctalia-shell quit or re-login)
• Open Noctalia Settings → Bar → Bar Widgets — stoa-doctor-pill and stoa-drive-pill should now appear in the list
• Enable both; verify pill colors and click popup menus work
