Force the local avatar out of Paint mode and block the switch key from
re-entering it while the match is in its resolution (reveal) window.
Painting is off for the local player regardless of role. No restore
needed: the match ends by despawning/respawning the avatar, rebuilding
the mode cycle at index 0.
