EDM-4784: Restore confirmation when user leaves dirty unsaved form - #853
In OCP v4.22, Prompt has been removed, which causes the LeaveFormConfirmation not to display any warning when the user abandons a form in the OCP plugin app.
New react-router versions only support this type of functionality for data routers, therefore we cannot rely on that.
We now implement our custom NavigationGuard to provide this functionality.
There are known limitations, as we now cannot reliably intercept the "Back/Next" browser buttons, but we'll provide a consistent experience for both applications through the Wizard's controls.
Made-with: Cursor
Summary
Added shared navigation-guard components in libs/ui-components/.
Restored confirmation for dirty, non-submitting forms in both applications.
Routed application links and custom navigation through the guard.
Added browser beforeunload protection while a form is dirty.
Removed Prompt and useBlocker from router context APIs.
Added controller unit tests. Test execution status is not available.
Updated apps/standalone/ and apps/ocp-plugin/ to provide the guard.
No changes affect libs/types/, libs/i18n/, libs/cypress/, proxy/, packaging/, or .github/workflows/.
No Go auth proxy, container build, authentication, or authorization changes are shown.
Browser Back and Forward interception is not provided. Guarded application navigation remains the supported path.
The shared component changes affect both standalone and OCP plugin applications.
Risk classification
Applied risk label: not available.
The supplied evidence does not include the labeling instructions or an applied risk label. The criteria for risk:ship, risk:show, and risk:ask are therefore unavailable. A near-miss classification cannot be established.
The change adds a shared navigation guard. Dirty forms register navigation locks, and guarded navigation can be confirmed or canceled. The OCP plugin and standalone app mount the provider. Router contexts no longer expose Prompt or useBlocker.

Summary
Guard state and registration libs/ui-components/src/components/common/NavigationGuardController.ts, libs/ui-components/src/components/common/NavigationGuardContext.tsx, libs/ui-components/src/components/common/NavigationGuardController.test.ts
The controller tracks registered locks and pending navigation. Context hooks expose guard state and lock registration. Tests cover navigation, lock counts, subscriptions, and pending-navigation behavior.
Guarded navigation and confirmation libs/ui-components/src/components/common/NavigationGuard.tsx, libs/ui-components/src/components/common/LeaveFormConfirmation.tsx, libs/ui-components/src/hooks/useNavigate.tsx
The provider shows a confirmation dialog when navigation is blocked and prevents beforeunload while locked. Dirty, non-submitting forms register locks. Link and useNavigate route navigation through the guard.
App provider wiring and router context libs/ui-components/src/hooks/useAppContext.tsx, apps/ocp-plugin/src/components/AppContext/AppContext.tsx, apps/standalone/src/app/hooks/useStandaloneAppContext.ts, apps/standalone/src/app/index.tsx
The OCP plugin and standalone app mount NavigationGuardProvider. Router contexts no longer expose Prompt or useBlocker.

The restored unsaved-changes confirmation covers only links and navigation built on the shared Link and useNavigate. In the standalone app, choosing a sidebar item while editing a form can still discard edits without a warning. Route sidebar navigation through the guard before merging.

- Line 9: Update NavItem’s sidebar navigation to use the existing navigation
guard instead of the unguarded NavLink, so the lock registered by
useRegisterNavigationLock(lock) can prevent leaving with unsaved edits; preserve

Guard standalone sidebar navigation.
When a user edits the repository form and selects a sidebar item, NavItem uses the unguarded NavLink. The route can change without a dialog, discarding the edits. Route sidebar navigation through the guard while preserving normal link behavior.

@celdrake I think this change introduced the leaveUnsavedForm CI regression: the test passed on its parent commit but fails on the PR branch because the unsaved-changes modal never appears. The sidebar’s NavItem still uses the router’s raw NavLink, which may bypass the new navigation guard.

@adalton Thanks for the report. Yes, there were some issues, I'll take a look at the failing test.
There are certain limitations as we are moving to having the same functionality in OCP plugin and Standalone app, so I'll review whether we can have the guard apply to both.
