Subject: [PATCH] viewer: give the current-image plot marker a fixed colour

The current-image marker (a scatter series) was picking an arbitrary theme colour
(green), which read as a stray series. Pin it to black so it's an unambiguous
"current image" dot, distinct from the run line colours. Its legend entry is
already hidden.
