Fix visibility change in statusbar

[AkibaAT]

The Problem/Issue/Bug:

Resolves issue #296

How this PR Solves the Problem:

Rework the status bar widget implementation to extend EditorBasedStatusBarPopup and StatusBarEditorBasedWidgetFactory respectively instead & remove code handled in the parent class
Use same static ID for the widget in DdevStatusBarWidgetImpl and plugin.xml

Manual Testing Instructions:

• ./gradlew build
• Install resulting build/distributions/ddev-intellij-plugin-0.0.1-dev.zip
• Toggling visibility of the ddev widget should work identical to all first-party widgets and cause no exceptions
• To test if the tutorial popup is still appearing properly, a tutorial reset might be required. This can be done by removing the got.it.tooltip.ddev entries from options/other.xml within the global IDE directory and restarting the program
  e.g. ~/.config/JetBrains/PhpStorm2024.2/options/other.xml for PhpStorm 2024.2 on Linux

Updated commit with regression fix, the widget wasn't hidden on non-ddev projects.

Sure thing!

One small side-effect I know about is that this version no longer prevents clicking on the the widget when DDEV is not in the running state. Instead it displays "Nothing here". Personally I didn't think that was worth re-adding the click handler again over, but I can certainly take another look if that's an issue.
