fix(nav): enable tooltips for local players during gameplay

Removed `pointerEvents: canModifyPlayers ? 'auto' : 'none'` from the active
players container that was blocking tooltips during gameplay.

During gameplay (canModifyPlayers=false), this was preventing hover events
from reaching the PlayerTooltip component, so tooltips wouldn't show for
local players. Network players didn't have this restriction, so their
tooltips worked fine.

The pointer-events restriction is not needed because:
- Interactive buttons (configure/remove) only show during setup (shouldEmphasize)
- Avatar click handlers already respect the shouldEmphasize flag
- Tooltips should always be accessible for player information
