[Bug]: Settings → Projects → All projects no longer shows Actions, so machine-wide default actions can't be edited #32519

Area

Steps to reproduce

1. Open Settings → Projects.
2. Set the "Project scope" picker to All projects.
3. Look for the Actions section to add an action that applies to every project.

Expected behavior

With All projects selected, the page shows an Actions section that edits the machine-wide default actions (defaultProjectScripts), as introduced in #9754 ("All projects edits machine-wide defaults"; screenshot "all projects defaults"). Projects without their own action list then inherit these defaults. This is also how #6523 (user-level actions for every project) was resolved.

Actual behavior

With All projects selected, the page only shows "Choose a project to manage its name, icon, checkouts and actions." There is no Actions section and no "Add action" button. The Actions section only renders inside the single-project view.

The setting itself still exists and is still resolved: the client resolver falls back to settings.defaultProjectScripts when a project has no override, and the settings search entry "Actions" still points to /settings/projects. So the machine-wide default is still used at runtime, but there is no UI left to create or edit it. The only way to set it is to hand-edit ~/.t3/userdata/settings.json.

Users who run the same actions in many projects now have to recreate them per project.

Impact

Major degradation or frequent failure

Workaround

Add each action per project via Settings → Projects → (pick a project) → Actions → Add action, or hand-edit defaultProjectScripts in settings.json.
