Collector config from the website

Provisioning a collector no longer means credentials over a side channel. Once the maintainer provisions your gateway, Account > Collector offers your complete configuration as a ONE-TIME download - it disappears from the server the moment you fetch it. You add exactly one thing yourself: your own Clash Royale API key. Pairs with the new Go collector: a single binary for Mac, Linux, and ARM NAS boxes, self-updating from signed releases.
