feat(mru): Implement Most Recently Used (MRU) functionality across plugins

- Added MRU support to SysPlugin and UrlPlugin, allowing users to access recently used commands and URLs.
- Introduced new data structures for MRU items and context data.
- Updated the query methods to include MRU results based on user settings.
- Modified the settings management to accommodate the new query mode for MRU.
- Enhanced the UI to reflect the changes in query modes and added relevant translations.
- Created a dedicated MRU manager for handling MRU items in the database.
- Updated Flutter UI to support MRU queries and settings.
