Handle missing WotLK packets: health/power updates, mirror timers, combo points, loot roll, titles, phase shift

- SMSG_HEALTH_UPDATE / SMSG_POWER_UPDATE: update entity HP/power via entityManager
- SMSG_UPDATE_WORLD_STATE: single world state variable update (companion to INIT)
- SMSG_UPDATE_COMBO_POINTS: store comboPoints_/comboTarget_ in GameHandler
- SMSG_START_MIRROR_TIMER / SMSG_STOP_MIRROR_TIMER / SMSG_PAUSE_MIRROR_TIMER: breath/fatigue/feign timer state
- MirrorTimer struct + getMirrorTimer() public getter; renderMirrorTimers() draws colored breath/fatigue bars above cast bar
- SMSG_CAST_RESULT: WotLK extended cast result; clear cast bar and show reason on failure (result != 0)
- SMSG_SPELL_FAILED_OTHER / SMSG_PROCRESIST: consume silently
- SMSG_LOOT_START_ROLL: correct trigger for Need/Greed popup (replaces rollType=128 heuristic)
- SMSG_STABLE_RESULT: show pet stable feedback in system chat (store/retrieve/buy slot/error)
- SMSG_TITLE_EARNED: system chat notification for title earned/removed
- SMSG_PLAYERBOUND / SMSG_BINDER_CONFIRM: hearthstone binding notification
- SMSG_SET_PHASE_SHIFT: consume (WotLK phasing, no client action needed)
- SMSG_TOGGLE_XP_GAIN: system chat notification
