fix(ui): use Govmap resolved address text for street inference, not frequency heuristic

Previous approach: pick most common streetNameHeb among street-source deals.
Problem: a busier nearby street wins even when the searched parcel is on a
quieter street (e.g. רב צעיר beats הילדסהיימר despite being a different street).

Fix: backend now returns resolved_address from Govmap autocomplete (e.g.
"הילדסהיימר 14, ירושלים"). Frontend parses the leading non-numeric tokens
as the street name and uses that as ground truth for proximity labeling.
