New /api/admin/ares proxy (browser cannot reach ares.gov.cz - CORS+CSP):
GET /ico/:ico and GET /search?q= map the MFCR REST API to the form
shape (street incl. orientation numbers, "511 01" PSC format, DIC).
Guarded by customers.create/edit + warehouse.manage; token errors map
to Czech messages. Shared AresAdornment button sits in the Nazev and
ICO fields of both modals: ICO mode fills directly, name mode searches
with a result picker. Tested against live ARES (BOHA, ICO 22599851).
