Record the deprecation of the observability endpoints on webServer in doc/deprecations.md, so the removal target is in one place next to the other active deprecations. The webServer /healthz, the frps webServer /metrics with its top-level enablePrometheus switch, and the pprof handlers with webServer.pprofEnable are deprecated since v0.72.0, when metricsServer was added. They are replaced by metricsServer, whose /healthz, /metrics and pprofEnable are independent of the dashboard listener.

## Features
|
|
|
|
* frpc can verify server certificates using system CAs, optionally combined with CAs from `trustedCaFile`.
|
|
* `frpc reload` now refreshes certificate files for unchanged `https2http` and `https2https` proxies without interrupting existing connections. Failed refreshes keep the previous certificate and report the error in proxy status and logs while reload still succeeds.
|
|
* Added `metricsServer` to both frps and frpc, a separate listener for health checks, metrics and optional profiling that does not expose the dashboard or the admin API. It is disabled unless `metricsServer.port` is set, defaults to `127.0.0.1`, and has its own credentials and TLS. Setting the port serves `/metrics` on both: frps exposes runtime and business metrics, so `enablePrometheus` is not needed there, and frpc exposes Go runtime metrics only, without linking an extra metrics library.

|
The `/healthz`, `/metrics` and pprof endpoints on `webServer`, `webServer.pprofEnable` and `enablePrometheus` still work but are deprecated: configure `metricsServer` instead. They will continue to work until v0.80.0 is released, and may be removed in v0.80.0 or later.

* Fixed proxy and visitor configuration changes being lost when reloading frpc during reconnection.
