feat(daemon, web): enhance plugin input handling and subcategory filtering

- Updated the `pickPluginFields` function to support legacy input aliases, improving compatibility with existing plugin structures.
- Added tests to ensure the new input handling works correctly with legacy inputs when resolving plugin snapshots.
- Enhanced CSS styles for subcategory elements in the plugin home section, improving visual clarity and user experience.
- Introduced new tests for subcategory filtering within the active workflow lane, ensuring accurate plugin categorization.

This update significantly improves the plugin management experience by enhancing input handling and refining the categorization system.
