FX.78 Tests: the team button sits in a folded panel section; add-on buttons are not registry commands

mounts-09 2026-11-06: tools/bimcraft-test/browser-r5.mjs clicked [data-model-team] while the shell's panel accordion had its section folded (a person opens the section first; the test now does too). tools/shell-test/browser-input-apps.mjs's "every toolbar button is a registry command" no longer lists add-on buttons (data-addon-tool), as print-09 asked; ModelCraft's 3D Print button passes. Still failing there, not from this session: "Move the Tools toolbar" (the toolbar tear grip) and the Settings style-card radio that is not visible; and tools/civil-mount-test/browser.mjs la4 clicks the first of two "Ground modifiers" menu items, which is hidden.
