feat(web): add machine tabs to project settings

[maria-rcks]

Project settings now open grouped projects on an All machines tab for shared values, with a tab per checkout for local grouping, actions, and removal controls. Machine tabs show only the machine name, and the redundant Project heading stays out of the multi-checkout layout.

Verified in the real app with two grouped checkouts; web typecheck, formatting, and targeted lint pass, while the focused existing Vitest suite remains blocked before collection by an undefined config access.

Note

Low Risk
UI-only scoping in project settings; checkout selection defaults to group-wide edits for multi-checkout groups instead of a single representative checkout.

Overview
Grouped projects with more than one checkout now use a horizontal All machines tab plus per-machine tabs instead of a checkout dropdown in the Checkout section.

All machines shows shared Project settings (name, icon, model, workspace, auto-pull) and Danger (remove everywhere). A machine tab shows Checkout details (path, grouping, actions, remove checkout). Single-checkout projects keep the previous layout with no tabs.

Machine tabs reuse provider-settings tab styling, show EnvironmentMachineIcon from each environment’s server config, and default selection to All machines (selectedCheckoutKey starts as null). User docs in project-settings.md describe the new scope.

Note

Replace checkout dropdown with machine tabs in ProjectSettingsPanel

• Replaces the checkout select control with a horizontally scrollable tab group in ProjectSettingsPanel.tsx, featuring an "All machines" scope and one tab per checkout.
• Shared project settings display under "All machines", while checkout-specific settings display under individual machine tabs.
• Updates project-settings.md to document the new scope behavior.
• Behavioral Change: The previous checkout dropdown is no longer rendered, and the Danger section is now only visible under the "All machines" scope.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — The PR adds a machine-tab workflow to project settings and changes multi-checkout projects to open in an “All machines” scope by default. It also conditionally hides checkout-specific and destructive controls based on the selected tab, making this a meaningful user-facing product behavior change.
