feat(boss): tint boss sprite outline by phase (P2 green, P3 red)

Add FlashSprite.setOutlineByBossPhase with light/dark green shade option and red fallback; BossPhaseSystem drives HeroViewComp.applyBossPhaseOutline directly after phase switch (MON faction, no hero-level event semantics, pool-node safe); extract getFlashSprite/applyOutlineByLevel to dedupe the three outline call sites.
