fix(web): Make Manage location utility header responsive

[Snowknight26]

Description

The Manage location utility page's header is cut off at smaller viewport widths, making the "Choose on map" and "Apply" buttons inaccessible. The header has been made more responsive by hiding some text at smaller viewport widths to allow for full functionality.

The casing of the Selected GPS Coordinates text has also been updated.

Fixes #21476

How Has This Been Tested?

• Viewed the Manage location utility page at different viewport widths
