fix: plugin card source badge blocked by hover overlay (#1802)

* Initial plan

* Add View Source menu item and remove clickable source badges

- Add "viewSource" translation key to all language files
- Add View Source menu item to plugin card dropdown (only for GitHub/marketplace plugins)
- Remove onClick handlers and ExternalLink icons from source badges
- Keep the badges themselves for visual indication of plugin source
