feat(system-builder): condition icons over tokens on the map (4e2b2)

[over2take]

From the approved builder-conditions mockup. Every token (enemy, friendly and player) draws its conditions as up to four icons above it, then +N; each icon is titled with its condition's name and +N lists the rest. Drawn for everyone, and whatever the game's token health, since a game without it may track harm in conditions alone. tokenConditions.ts mapIcons holds the four-then-+N rule.

useConditionList now shares one request per game and login across every window and token, forgets a failed request so the next asks again, and forgets them all once (at module level, before any hook re-asks) when a published system changes, so a map of many tokens asks once.
