Slack Install Callback

GET 
/channels/catalog/channels/slack/callback/

Slack redirects the browser here, in or out of the session that started the install -- the signed state is the whole of the authorisation on this route, so this is public (see _PUBLIC_ENDPOINTS), never self._check. State decodes first: unknown, expired or tampered refuses before any exchange is attempted.
