ci: Add screenshot validation and navigation bar test

* Introduced screenshot validation using `Remote Weston Capture Screenshot`
  and `Remote Weston Check Screenshot` keywords.
* Implemented a new test: `Test Check Navigation Bar` to verify navigation
  bar transitions using screenshots.
* Updated dependencies in `keywords_common.robot` to include `DocTest.VisualTest`.
