refs https://github.com/TryGhost/Ghost/issues/6949 Handle version mismatch errors by: - displaying an alert asking the user to copy any data and refresh - disabling navigation so that unsaved data is not accidentally lost Detailed changes: - add `error` action to application route for global route-based error handling - remove 404-handler mixin, move logic into app route error handler - update `.catch` in validation-engine so that promises are rejected with the original error objects - add `VersionMismatchError` and `isVersionMismatchError` to ajax service - add `upgrade-status` service - has a method to trigger the alert and toggle the "upgrade required" mode - is injected into all routes by default so that it can be checked before transitioning - add `Route` override - updates the `willTransition` hook to check the `upgrade-status` service and abort the transition if we're in "upgrade required" mode - update notifications `showAPIError` method to handle version mismatch errors - update any areas where we were catching ajax errors manually so that the version mismatch error handling is obeyed - fix redirect tests in editor acceptance test - fix mirage's handling of 404s for unknown posts in get post requests - adjust alert z-index to to appear above modal backgrounds
