Add progress spinner while checking single addon

[chennes]

Update checks happen automatically on startup (for most addons it is just part of the supplied metadata in the catalog, only custom addons need to be checked at their source). In rare circumstances something might happen to interrupt this: if that happened, automatically run an update check when the addon's detailed view is shown, and display a small spinner to indicate that is happening.

Pull Request Overview

This PR adds a visual progress spinner to indicate when an addon is being checked for updates in the detailed view. The implementation replaces the previous "Check for Update" button with an animated spinner widget that appears automatically when update checks are in progress.

Key changes:

• Created a new reusable Spinner widget with SVG-based animation and automatic foreground/background color detection
• Integrated the spinner into the addon button bar to replace the manual update check button
• Added automatic spinner activation when addon status is UNCHECKED and deactivation when checks complete

[nitpick] The os import is only used once for path joining. Consider using pathlib.Path instead for better cross-platform compatibility and more modern Python practices.

Suggested change

	import os
	from pathlib import Path

Hard-coded relative path '../Resources/icons/spinner.svg' may break if the file structure changes. Consider using a more robust path resolution method or making the spinner icon path configurable.

The paintEvent method creates a new QImage, QPainter, and performs SVG rendering on every paint cycle. Consider caching the rendered image and only regenerating when the angle changes significantly to improve performance.

The spinner is started before checking if self.update_check_thread exists. If thread creation fails after this point, the spinner will remain visible indefinitely. Move this call after successful thread creation or add proper error handling.
