InternetChecker class

Performs real Internet reachability checks against one or more HTTP(S) endpoints.

Connectivity type alone (Wi-Fi, mobile) does not tell you whether the device can actually reach the Internet — captive portals, router misconfiguration, or a local-only network can all report a connected link with no upstream access. This class answers that question directly, with configurable endpoints and fallbacks so a single provider outage isn't mistaken for "no Internet".
