fix(map): skip labels on worked cells — bright-yellow 4-char text on green fill read as 'green too bright'

The previous fix skipped grid LINES through worked cells, but each worked cell
still got a bright-yellow (alpha 220 + black shadow) 4-char label drawn dead
center on the green fill at zoom>=7. Field zoom never shows this because 2-char
labels sit at field centers and almost never overlap a worked 2x1 square. Now
worked cells stay completely label-free, matching the field-zoom look.
