plasma: ESC P bitmap rows through the feedback endpoint (plasma row)

Browse Source 
PlasmaCommands.GraphicsWrite/GraphicsRow port the display firmware graphics
command (ESC P s y x w h, MSB-left); PlasmaDisplay.RowAsync writes a locked
whole-row update; the line protocol gains `plasma row <y> <hex32>`. The
router plasma slot becomes a bounded FIFO queue: rows stream in order (a
frame must not tear), texts still coalesce to the newest, clear flushes, cap
128 with counted drops. Docs updated; 442 tests.
