debug: fix data race in Debug::log() (#11931)
* debug: fix data race in Debug::log()
The templated Debug::log() had mutex protection but the non-template
overload it calls didn't, causing crashes when plugins called log from
background threads (like hypr-dynamic-cursors loading cursor themes).
Fixed by moving the mutex lock from the template version into the
non-template version, so all writes to shared state are protected.
Fixes: hyprwm/Hyprland#11929
Fixes: VirtCode/hypr-dynamic-cursors#99
* debug: apply clang-format to Log.cpp
Fix formatting to satisfy CI clang-format check.
