feat(world): serve local location view content from the API

Adds the server side of the local location view: location_definitions
carries region naming, a location type, a scene-level description and
artwork, plus JSONB points of interest, primary actions and a reward
preview. Locations become content, so a second location renders through
the same components with different data.

GET /api/world/current-location gains those fields, a recommendation
label and a danger rating derived from the weighted average of the
location's own monster pool — a rare elite no longer makes a beginner
road read as lethal. The encounter preview is derived from that same
pool rather than duplicating it.

POST /api/world/current-location/interactions/:key reveals a hotspot's
authored result. The location is resolved from the character, never from
the request, and result text never ships with the location payload, so a
caller cannot read or trigger a hotspot it has not travelled to.

Seeds the Verbrannte Straße with its four hotspots and the Südtor with
its own transition content. Adds Verwilderter Straßenhund and Verkohlter
Plünderer to the road's pool, including combat sprites, so the preview
shows encounters the hunt can actually roll. Medallion icons move to
images/monsters/icons, where both combat and the location view read them.
