fix: mode-line tooltip shows location in lowercase

wttr.in's %l format returns locations in lowercase (e.g.,
"new orleans, la") regardless of the query casing. Replace the API's
location prefix with the user's original wttrin-favorite-location
string at cache time so tooltips display what the user expects.
