Updated header markup to remove 'd-none' class from 'EMERGENCY' span

[TARUN2K3]

Description

Removed the 'd-none' class from the 'EMERGENCY' span within the header section to ensure the text is visible. The 'd-none' class was replaced with the 'd-md-inline' class to maintain responsive behavior, displaying the text on medium and larger screens while hiding it on smaller screens.
