fix(frontend): HandleServerTravelRequested idempotente quando ja no mapa certo

Browse Source 
Cliente fazia OpenLevel 2x:
1. CharSelect resolve mapId via DT_Maps -> TravelToMapById -> OpenLevel
2. Server confirma com S_TRAVEL_TO_MAP -> HandleServerTravelRequested ->
   OpenLevel **de novo**

O segundo OpenLevel destruia o World, PlayerState, AttributeComponent e HUD
que ja tinham sido criados/bindados. AttributeComponent novo iniciava com
snapshot vazio (entity=0, level=1, hp=0/0) — HUD ficava nesse default.
S_ATTRIBUTE_SNAPSHOT_FULL com dados reais chegava DEPOIS do reload, mas
HUD nao tinha sido recriado/reativado no novo mundo, entao HandleAttributesChanged
nunca rodava.

A deduplicacao em ZeusNetworkSubsystem (`S_TRAVEL_TO_MAP duplicate ignored`)
so pegava do 3o TRAVEL em diante — o 2o ja fazia o estrago.

Fix: compara nome curto do World atual (strip prefixo UEDPIE_N_ do PIE) com
o target. Se ja' estao no mesmo mapa, skipa OpenLevel e so seta state pra
InWorld — preservando HUD/PlayerState/AttributeComponent.
