fix(proxies): render configured groups in global mode (#8402)

* fix(proxies): render configured groups in global mode

Global mode previously only rendered the synthetic GLOBAL group and
sliced off its header, which flattened every user-defined group into
a non-expandable proxy row. Configured groups could no longer be
opened or inspected. Render the same group list as rule/script mode
so every group keeps its own header and expand toggle.

Fixes #8376

* style: keep useRule assignment on one line

* fix & changelog

* fix: hover when global proxy
