feat(ipinfo): support the Lite API for free/Lite plan tokens (v1.1.0)

The integration only exposed the Core API (/lookup/*), which returns 403
for accounts on the free/Lite plan — including the instance Test button.

Add the Lite endpoints: lite_lookup_ip (GET /lite/{ip}), lite_lookup_me
(GET /lite/me) and lite_batch (POST /batch/lite, code-first because the
endpoint takes a raw JSON array; chunked at the documented 1000-IP cap).

Point test_connection at /lite/me: every plan can reach it, so the token
check now succeeds on Lite-only accounts while still validating Core ones.
Core commands keep their paths and state the plan requirement up front.
