Release 3.9.0+3: subscription-URL routing, emoji flags, Remnawave provisioning.

Route credential-less http(s) URLs pasted into the add-link field to
subscription import (fixes remaining 'proxy URI missing username').
Extend geoflag with RU country names and city hints; live Remnawave
names already carrying emoji flags are kept as-is. Add admin
provisioning via configs/remnawave-api.json (GET by-username / POST
users, 50 GB MONTH plan) and the «Выдать доступ» UI panel.
