feat(Clusters): allow add, edit and delete cluster funcs

[artemmufazalov]

Part of #2333

• Add onAddCluster, onEditCluster, onDeleteCluster options to uiFactory
• Rework header - now it's shown on Clusters page, it can contain "Add Cluster" button
• Remove clusters statistics
• Add menu with edit and delete buttons to Clusters table

Clusters page is not fully redesigned according to design, I only make changes that allow to add buttons

Design: https://nda.ya.ru/t/-uEByWGb7F6QxM
Example how it will work: https://nda.ya.ru/t/EyvbNXsb7F7iRc

Pull Request Overview

This PR implements create/edit/delete cluster functionality in the UI by adding new capability endpoints, hooks, header actions, and table menu items, while removing the old cluster statistics view.

• Introduce /meta/create_cluster, /meta/update_cluster, /meta/delete_cluster capabilities and corresponding hooks (useAdd/Edit/DeleteClusterFeatureAvailable)
• Extend the header: add “Add Cluster” button on the Clusters page and update breadcrumb logic to include a root “All clusters” link
• Update the Clusters page: remove statistics component, add a dropdown menu for edit/delete actions in the table, and adjust layout

src/containers/Clusters/i18n/ru.json:1

• Russian translations for the clusters page were removed; re-add the ru.json file or merge these translations back to maintain Russian localization support.

{

src/containers/Clusters/i18n/index.ts:3

• Removed the RU keyset import; this breaksover Russian localization for the clusters page. Consider restoring the ru keyset registration.

import ru from './ru.json';

src/store/reducers/capabilities/hooks.ts:127

• New feature hook useAddClusterFeatureAvailable lacks unit tests verifying its behavior; consider adding tests to cover feature-version lookup logic.

export const useAddClusterFeatureAvailable = () => {

src/containers/Header/Header.tsx:61

• Rendering logic for the “Add Cluster” button is new UI behavior and should be covered by component tests to catch potential regressions.

if (isClustersPage && isAddClusterAvailable) {

src/containers/Clusters/i18n/en.json:21

• [nitpick] The UI label uses “Remove Cluster” but the API hook is named onDeleteCluster. Consider renaming the key and label to “delete-cluster” for consistency.

"remove-cluster": "Remove Cluster"

Is it possible to set it as default value in store instead of useEffect here?

[artemmufazalov]

1. It is not a default value, there is no clusters page in single-cluster version
2. useEffect is needed here anyway to reset current breadcrumbs state. So even if it will be a default value, some function call will be needed

[astandrik]

maybe if onEditCluster is undefined - we also shouldnt push this to menuItmes

currently its kinda unobvious how onEditCluster and isEditClusterAvailable are connected or related to each other

[artemmufazalov]

We check it when we define these vars

const isEditClusterAvailable =
     useEditClusterFeatureAvailable() && uiFactory.onEditCluster !== undefined;
const isDeleteClusterAvailable =
     useDeleteClusterFeatureAvailable() && uiFactory.onDeleteCluster !== undefined;

uiFactory.onEditCluster?.() here is because we do not check type here

[artemmufazalov]

Fixed, it should look better now
