fix(boss): keep phase outline authoritative over level tint and pool reuse

Reuse existing outline-green/outline-glow materials (P2 green / P3 red); phase outline now takes priority over level tint during boss lifetime (init/lv_up both route through BossPhaseComp), and HeroViewComp.reset clears the material back to default so pooled monster nodes never inherit a boss's red/green edge.
