fix(proxy): show a profile-defined GLOBAL in rule mode when it is the only group (#8607)

* fix(proxy): show a profile-defined GLOBAL in rule mode when it is the only group

Rule mode renders only proxyView.groups, and the backend always moves
GLOBAL out of that list. A profile whose only group is GLOBAL, or that
has no proxy-groups, therefore showed the "no proxy info" empty state.
Fall back to GLOBAL in that case, as v2.5.2 did before #7542.

Fixes #8223

* docs(changelog): note the rule-mode GLOBAL fix

* chore: drop the regression test and append the changelog entry

Per review: the test was only needed to confirm the fix locally, and new
changelog entries go at the end of their list.
