From bd61e0391aaf8a15b305049ef1b9eb47096d69ef Mon Sep 17 00:00:00 2001
From: Clarence12138 <148194843+Clarence12138@users.noreply.github.com>
Date: Thu, 17 Sep 2026 03:30:54 +0800
Subject: [PATCH] feat(settings): configure global and per-proxy request
 location (#123)

* feat(proxies): configure per-proxy request location

* feat(settings): manage global request timezone and location

Move request location from YAML into runtime settings with an enable switch. Preserve client fields when disabled and keep per-proxy overrides first. Share location inputs and simplify proxy and settings controls.
