An admin can save how many reverse proxies stand in front of Grimoire.
A saved count wins over TRUSTED_PROXY_HOPS, which stays the starting
value. Each worker loads it at startup (under a deadline) and re-reads
it every 30s; the worker that saves applies it at once.
GET/PUT /api/admin/proxy returns the count, where it came from, and a
readout of the admin's own request: the socket peer, the forwarding
chains, what counts 0-3 would read, and the count that reads
Cloudflare's visitor when Cloudflare's headers are present. Saves are
audit-logged. A "too many attempts" reply now says where to look when
everyone is being blocked.
