Replaces the Worker+KV approach (which only covered the ~27 routed hosts) with a
zone-wide mechanism that covers ALL proxied hosts: two CF account IP Lists
(crowdsec_ban, crowdsec_captcha) + one zone WAF custom rule that blocks
`(ip.src in $crowdsec_ban)` and managed-challenges `(ip.src in $crowdsec_captcha)`.
No per-request Worker, no cookie machinery — the rybbit Worker stays
analytics-only. lapi_kv_sync.py now full-reconciles the two lists from LAPI
(fail-safe: a LAPI blip skips the run and freezes the last-known-good block set;
serializes CF bulk ops since CF allows one pending op per account). A
least-privilege CF API token (Account Filter Lists Edit) is minted in TF.
