fix: force white color for Login link in production with !important
The Login link was appearing light blue and nord purple when visited
in production/preview builds due to CSS specificity conflicts with
global nordtheme.css link styles. Added !important flags to enforce
white color for all link states and nord8 for hover/focus states.
