The Ontario 511 camera list answered 400 "Invalid Key" on every catalog load
("[CCTV] Ontario 511 camera download failed: 400"), so the pack loaded
nothing. 511on.ca's developer docs now say the API "Requires a developer
key" (free, from 511on.ca/developers; 10 calls a minute). The loader reads
ONTARIO_511_API_KEY and sends it as `key`; without it the pack is skipped
with one log line instead of a failed request on every load. The key is
never logged. .env.example and DATA_SOURCES no longer call the endpoint
keyless.
