case 4732 - trusted reverse proxies setting

Browse Source 
New config setting AYANOVA_TRUSTED_PROXIES (IP addresses or CIDR networks)
for reverse proxies on another computer: their X-Forwarded-For is used, a
chain of trusted proxies is followed, invalid entries are warned at boot.
X-Forwarded-For from a proxy that is not trusted logs one warning per server
start naming the proxy's address. Without the setting nothing changes (only
a loopback proxy is trusted). Shown in server info; manual page, Linux install
note, changelog. F6 follow-up recorded.

| 4726 | Login throttling/lockout (raven and sockeye) | F6. **Done**; the Sockeye half (`6d6c74f`), like 4710's, takes effect when Sockeye is deployed to its droplet (10 failures per login or 50 per address in 15 minutes, then 429 for the rest of the window; same in Sockeye, whose login is public; test `LoginLockout`; per-address limit proved with a forwarded documentation address) |
| 4727 | Low severity hardening | F10, F11, F12, F22, F23, F25, F29, F35, F36, F38; the AyaNova half of F39 (DB ID not shown anonymously). In steps: 1 logo (F23) **done**; 2 API root page (F11, F39) **done**; 3 `server-info` (F29) **done**; 4 template export (F22) **done**, job owner check accepted; 5 `OverrideUserId` and export download (F25) **done**; 6 safe headers (F35) **done**; 7 remove `dist/docker` (F38) **done**. All steps done; outside this repo, for `sockeye-client`: bind `127.0.0.1`, the `chmod`, the systemd options (F36, F38) |
| 4681 | Sockeye: licence/trial request hardening (tagged sockeye, rockfish) | F40. **Done** (sockeye `cd3ebed`: rate limits, email check, cryptographic codes; rvf unchanged) |
| 4732 | Trusted reverse proxies setting (from the Sockeye migration runbook, Appendix A) | F6 follow-up. **Done** (`AYANOVA_TRUSTED_PROXIES`: addresses or CIDR networks, chain followed, invalid entries warned at boot; one log warning per start when `X-Forwarded-For` comes from an untrusted proxy; manual page and changelog. Proved by hand through the LAN address: not set, logins recorded as the proxy and the warning logged; set, the forwarded client address used, a forged extra entry ignored, a two-proxy chain followed; localhost unchanged. Not needed in Sockeye: its nginx connects on loopback) |
