feat: add clear/cross button to Forum search box (#1528)

[Akshita-2307]

Closes #1528

Problem

Forum search box has no way to instantly clear the entered text.

Changes

• Added a clear/cross (X) button that appears when text is entered
• Clicking the button clears the search text and refocuses the input

Hi @Akshita-2307, thank you for creating the PR, but you made a mistake by creating the PR directly without getting assigned to the issue. This is not the correct workflow for contributing to open source projects. However, I am accepting this PR for you this time; otherwise, I usually close PRs that are not associated with an assigned issue.

• The PR you created looks correct, but according to the issue, could you please explain how migration.yml is related to this issue and what its purpose is in this context?

[Akshita-2307]

Cleaned up the branch — dropped the two unrelated commits (testimonial carousel fix and migration issue template) that leaked into this PR. The branch now contains only the single commit for the forum search clear button.

The migration.yml you asked about was included by mistake from a different working session. It has been removed from this PR.
