* feat(tray): add a per-group latency test
The tray's proxy group submenus offered no way to test a group: refreshing
the delays shown there meant opening the dashboard and running a test from
the proxy page.
Add a "Test Latency" entry at the head of each group submenu. It measures
the group through the proxy page's own view, so member resolution and
provider attribution match the page exactly: provider nodes are health
checked on their provider, anything else goes through the proxy delay
endpoint, and members the page cannot resolve are skipped. Nested groups
are therefore tested through their currently selected node, as the page
does. The menu is rebuilt when the run finishes.
The test URL follows the page's chain -- the group's own test URL, then the
configured default, then the built-in one -- including the page's validity
check, so a group with a malformed URL falls back where the page falls back.
A group test started from the app rebuilds the tray as well, so the two
views do not drift.
