[management,signal,proxy,relay,misc] Unify service configuration loading
...
Service entry points currently resolve defaults, files, environment variables, and flags differently, which makes precedence inconsistent and prevents some services from using config files.
Introduce one Viper-backed loader and migrate Combined, Management, Relay, Signal, and Proxy while preserving compatibility aliases and Management template expansion.

[relay] only trust X-Real-Ip headers from configured trusted proxies ( #6833 )
...
The WS listener unconditionally trusted X-Real-Ip/X-Real-Port headers,
letting any client forge the source address the relay logs. Gate header
trust behind a trusted-proxy allowlist; ignore the headers unless the
immediate peer matches a configured prefix. Defaults to never trusting
the headers when the allowlist is empty.

## Summary by CodeRabbit
* **New Features**
* Added `--trusted-proxies` to configure a comma-separated allowlist of
trusted upstream proxy IPs/CIDRs.
* **Behavior Changes**
* Relay WebSocket now uses `X-Real-Ip` / `X-Real-Port` only when the
immediate peer is from the configured trusted set; otherwise it falls
back to the direct remote address.
* Proxy client IP resolution is now consistent and honors
`X-Forwarded-For` only through trusted hops.
* **Operational**
* Invalid `--trusted-proxies` values fail fast on startup.
