WHITELIST_ALWAYS started with a comma, so exploding it produced an empty first entry and isAppWhitelisted('') returned true. getRequestedApp() returns an empty string whenever IAppManager::cleanAppId() strips the path segment down to nothing, which made those requests pass the allowlist check.

Config::getAppWhitelist() had the same problem: exploding an empty setting yields a single empty entry, which was both whitelisted and rendered as a blank chip in the admin settings.
