fix: search geocode now includes viewport bias in API requests

Browse source 
Symptom: HAR capture showed /api/geocode requests with NO lat/lon/zoom
params despite map being centered on Twin Falls. Results returned
out-of-state addresses (Illinois, Iowa, Arkansas).

Root cause: SearchBar subscribed to mapCenter via React hook, but the
value was stale at search time due to render timing.

Fix: api.js searchGeocode now reads mapCenter directly from the store
via useStore.getState() at call time. This is the correct pattern for
non-component code. SearchBar no longer passes mapCenter as a param.
