Subject: [PATCH] Dynamic profile lookup from auth connection

Profile name is returned by ensureAuth() from the auth connection
(looked up by domain). No more storing profile names in settings.json
for the applier flow. createBrowser() still supports legacy platform
keys as fallback for searcher/setup.
