Enhance status component and dashboard functionality

- Updated the status component template to include a new trigger for task status checks.
- Modified the status component's Go implementation to reflect the new trigger in the HTML output.
- Improved the UpdateIssue handler to conditionally set the assignee based on form input.
- Enhanced the dashboard template to include a new dependencies section for issues, allowing users to add dependencies dynamically.
- Refactored the dashboard's issue rows to utilize JavaScript functions for rendering status, type, and priority badges, improving maintainability and readability.
