feat(postcodes/VI): 6 USVI ZIPs (#1039)#1524

Conversation
Mirrors VI-mapped ZIPs from US.json into the separate USVI country
namespace, FK'd to nearest USVI city by centroid distance.
Why
---
USVI uses US ZIPs in the 008xx range, but CSC represents USVI as
its own country (iso2=VI, country_id=242) with 3 island states
(Saint Thomas / Saint John / Saint Croix). Without this mirror,
postcode lookups for VI return empty.
Coverage
--------
- 6 ZIPs / 100% state FK
- All 3 USVI states represented (ST: 00802, SC: 4 codes, SJ: 00830)
State FK strategy
-----------------
Centroid-distance matching against cities/VI.json (20 USVI
localities), then FK to that city's state_id (one of 3 islands).
License
-------
Original source: US Census ZCTA (CC-0).
Each row: source: "us-census-via-vi-mirror"
Validation
----------
- python3 -m py_compile passes
- 100% regex match (^008\d{2}(?:-\d{4})?$)
- 100% state_id valid + state.country_id == 242 + state_code agrees
- No auto-managed fields (id, created_at, updated_at, flag)
