Summary

This pull request significantly expands and enhances the test coverage for the Marketmate project card and its gallery modal in the WhoamiLiveProjectsTest suite. It introduces comprehensive tests for the modal's behavior, navigation, and UI elements, as well as utility functions to support these tests. There are also minor updates to versioning and improvements to existing helper functions.

Marketmate Gallery Modal and Project Card Testing:

• Added a new test suite covering the Marketmate gallery modal, including tests for modal rendering, navigation (next/previous buttons and thumbnail selection), video preview, source link, modal dismissal (via button and backdrop), and UI behavior (hiding navigation buttons at boundaries).
• Added tests to ensure the Marketmate card uses a video preview and is rendered as a button without a duplicate card badge. [1] [2]

Helper and Utility Function Enhancements:

• Introduced new helper functions has_tag_with_src_containing?/3 and has_tag_with_attribute?/3 to facilitate DOM assertions for video and attribute presence in test trees.
• Updated the has_backdrop_close?/2 helper to accept an event name, improving its flexibility and reusability. [1] [2] [3]

General Improvements:

• Updated the project version in mix.exs from 1.3.0 to 1.4.0.

These changes improve the reliability and maintainability of the test suite, especially around interactive UI components.
