"No colour on worked" blanked the spot status as well as the worked-call flag,
on the theory that a spot bringing no novelty should stop painting entirely.
But the status is exactly what the cluster list reads to DIM a row. Blanking it
made isDull() fall through its "unresolved, never dim" guard, so every quiet grey
row came back at full brightness. The option meant to calm the list was the one
making it shout. It also forced a `muted` flag to exist purely so tooltips could
say that an empty status did not, this time, mean "entity not resolved".
It now removes the blue already-worked mark and nothing else, which is all it
ever needed to do: a worked entity already renders with no colour of its own and
is already dimmed. The flag, its two tooltip strings and the special-cased band
map styling all go with it.
