Add Release Notes entry to the settings menu (#3005)

This adds a **Release Notes** action to `SettingsFloatingWindow` in the
requested position: after **Secrets** and before **Help**. It also wires
that action to open the existing `onboarding-upgrade-patch.tsx` UI as a
standalone modal, so release notes remain accessible even when automatic
upgrade onboarding would not render for up-to-date clients.

- **Settings menu**
- Adds a new **Release Notes** item to
`frontend/app/workspace/widgets.tsx`
  - Places it between **Secrets** and **Help**
- Uses the existing modal system rather than creating a new view/block
path

- **Release notes launch path**
  - Registers `UpgradeOnboardingPatch` in the modal registry
- Opens it from the settings menu via
`modalsModel.pushModal("UpgradeOnboardingPatch", { isReleaseNotes: true
})`

- **Standalone modal behavior**
- Extends `UpgradeOnboardingPatch` with a lightweight `isReleaseNotes`
mode
- In release-notes mode, closing the modal pops the stacked modal
instead of toggling `upgradeOnboardingOpen`
- Preserves the existing automatic upgrade-onboarding flow and version
metadata update behavior for the original path

```tsx
{
    icon: "book-open",
    label: "Release Notes",
    onClick: () => {
        modalsModel.pushModal("UpgradeOnboardingPatch", { isReleaseNotes: true });
        onClose();
    },
}
```
