Vietnam dropped the district administrative level in the 2025 reform
(Nghị quyết về sắp xếp đơn vị hành chính). Only two levels remain:
province (level=4) and ward/commune (level=6).
OSM has updated tagging accordingly: every former xã/phường/thị trấn
that survived the merge is now `admin_level=6`, no `admin_level=8`
features for VN. Our sync confirmed this — 3,189 level=6 units inserted
across 33 provinces, level=8 returns zero.
The schema column "vn_districts" stays as-is to avoid a cascade-rename
across IndustrialPark / ProjectDevelopment / Property FKs. Documented
the semantic shift in osm-data-model.md so future ops don't think
something is broken when wards are empty.

* Listing detail: drop the new <NearbyPoiSidebar> below the price card
with default 1.5km radius and 6 categories (school/secondary/hospital/
market/bank/metro). Reads property.lat/lng — no-op when unset.
* KCN detail: same component but 3km radius with the categories that
matter for industrial parks (hospital/bank/gas/bus/metro/police).
* New <PoiSearchFilter> widget for the search page: pill button →
popover with radius dropdown (300m..5km), 3 quick presets ("Family",
"Commute", "Convenience"), and 6 grouped category checkboxes. Wires
to a `PoiNearbyConstraint` value so callers can pass it into search
filters when they're ready.
* docs/osm-data-model.md: canonical reference for every OSM-sourced
table, sync cadence, quality gates, runbook for ops, and a clear
"how to add a new POI category" guide.
