feat: add hunt page, combat placeholder, and Jagd navigation

Wires up Slice 0.2 end-to-end: HuntPageComponent renders the
hunting-unavailable/ready/loading/encounters-found states off
HuntingStore and WorldStore, Angreifen hands the HuntEncounter id to a
new inert CombatPlaceholderPageComponent via /combat/new, the Jagd nav
entry is enabled with router-driven active state (matching Karte's),
and the context panel now lists possible encounters for hunting-enabled
locations.
