Coaches reviewing a match over a screen share pause on a moment and want to
circle a player or show where someone should have gone. Until now the only
way to draw was to capture the moment and open it in the editor.

The match card gets a pen next to Capture (and the D key). Taking it out
pauses playback and shows two tools, freehand and a straight arrow, plus
Clear once something is drawn. Esc, D or the pen again put it away; the
strokes stay until cleared or until the moment changes: playing clears them
and puts the pen away, seeking or changing round clears them.

Strokes are the editor's own drawing elements (FreeDrawing, Line with an
arrowhead) in the attack-side world, drawn by the editor's DrawingPainter in
the user's last editor pen colour and thickness, in a layer of its own above
everything on the map. The layer is flipped on defense as the editor flips a
page's drawings, zooms and pans with the map, and repaints only when the
strokes change. While the pen is out a drag draws instead of panning; the
wheel still zooms. The strokes live in the replay screen's own state, never
in the editor's drawing providers.

Capture saves them as the page's drawings, on both paths: locally as
StrategyPage.drawingData, in the cloud as ordinary drawing elements through
the existing page ops. No saved format, Hive model, export or server change.

DrawingPainter loses a provider parameter it never read, so the replay can
paint with it.
