Rewrite to use Ubiquiti's public cloud API at api.ui.com instead of
logging into individual controllers via session cookies. Benefits:
- One API key covers every UniFi OS device on the account (no
per-controller login logic, no cookie jar lifecycle).
- Read-only by design (auth keys are scoped).
- Works across sites transparently.
Three endpoints wired up: hosts (controllers / Cloud Keys), sites,
and devices (APs / switches). Each emits a distinct TSV shape so the
output can be concatenated and still parsed.
`all` mode runs all three and prints section markers on stderr so
the stdout stream stays clean TSV suitable for discover-gaps.sh.
Pagination handled via nextToken. Rate limit not enforced locally;
Ubiquiti documents generous defaults for read endpoints.
Note: Site Manager API (early access) doesn't appear to expose a
connected-client list directly. For endpoint discovery (IP + MAC of
connected clients like laptops, IoT, etc.) we'd still need to hit
each local controller's REST API — follow-up if the infrastructure-
level data isn't enough.
Requires: curl (present), jq (apt install jq).
