Behind a reverse proxy (e.g. nginx with X-Real-IP), admin audit logs and
session IP/UA binding always recorded 127.0.0.1 because they hardcoded
the gin trusted_proxies chain, while API key IP restriction already
honored the "trust forwarded client IP" system setting.
- add ip.GetSecurityClientIP(c, trustForwarded) as the single source of
truth for security-sensitive client IP selection; API key auth
middlewares (main + google) refactored onto it with zero behavior change
- SessionBindingContext(cfg) now resolves the client IP via the same
toggle and injects it into the request context; token issuance,
binding enforcement and its mismatch audit record all read the
injected value, so issue/verify can never diverge
- audit log middleware and audit-log clear trace record the same
security client IP (middleware.SecurityClientIP), falling back to the
trusted proxy chain when the injection is absent
- settings UI hint (zh/en) documents the broadened toggle scope and the
one-time re-login after toggling while session binding is enabled
With the toggle off (default) behavior is byte-for-byte unchanged.
