fix(map): own grid never striped — bold outline only

The station's own gridsquare is in the roamed set (LoTW MY_GRIDSQUARE includes
the home grid). Exclude it from the blue stripe overlay at both zoom levels so
the current cell shows only its bold cyan outline, matching the user's request.

chore: bump version to 4.4.6-ba7opf.10
