feat(backups): use zip CLI for file restore

Much faster and memory efficient than the previous implementation.

Downside is that it requires `zip` from being installed on the system.

-# XenApiCollection
-
-## Get the collection
-
-To retrieve a collection, invoke `useXenApiCollection("VM")`.
-
-By doing this, the current component will be automatically subscribed to the collection and will be updated when the
-collection changes.
-
-When the component is unmounted, the subscription will be automatically stopped.
-
-## Defer the subscription
-
-If you don't want to fetch the data of the collection when the component is mounted, you can pass `{ immediate: false }`
-as options: `const { start, isStarted } = useXenApiCollection("VM", { immediate: false })`.
-
-Then you subscribe to the collection by calling `start()`.
-
-## Create a dedicated collection
-
-It is recommended to create a dedicated collection composable for each type of record you want to use.
-
-They are stored in `src/composables/xen-api-collection/*-collection.composable.ts`.
-
-```typescript
-// src/composables/xen-api-collection/console-collection.composable.ts
-
-export const useConsoleCollection = () => useXenApiCollection("console");
-```
-
-If you want to allow the user to defer the subscription, you can propagate the options to `useXenApiCollection`.
-
-```typescript
-// console-collection.composable.ts
-
-export const useConsoleCollection = <
-  Immediate extends boolean = true,
->(options?: {
-  immediate?: Immediate;
-}) => useXenApiCollection("console", options);
-```
-
-```typescript
-// MyComponent.vue
-
-const collection = useConsoleCollection({ immediate: false });
-
-setTimeout(() => collection.start(), 10000);
-```
-
-## Alter the collection
-
-You can alter the collection by overriding parts of it.
-
-### Example 1: Adding props to records
-
-```typescript
-// xen-api.ts
-
-export interface XenApiConsole extends XenApiRecord<"console"> {
-  // ... existing props
-  someProp: string;
-  someOtherProp: number;
-}
-```
-
-```typescript
-// console-collection.composable.ts
-
-export const useConsoleCollection = () => {
-  const collection = useXenApiCollection("console");
-
-  const records = computed(() => {
-    return collection.records.value.map((console) => ({
-      ...console,
-      someProp: "Some value",
-      someOtherProp: 42,
-    }));
-  });
-
-  return {
-    ...collection,
-    records,
-  };
-};
-```
-
-```typescript
-const consoleCollection = useConsoleCollection();
-
-consoleCollection.getByUuid("...").someProp; // "Some value"
-```
-
-### Example 2: Adding props to the collection
-
-```typescript
-// vm-collection.composable.ts
-
-export const useVmCollection = () => {
-  const collection = useXenApiCollection("VM");
-
-  return {
-    ...collection,
-    runningVms: computed(() =>
-      collection.records.value.filter(
-        (vm) => vm.power_state === POWER_STATE.RUNNING
-      )
-    ),
-  };
-};
-```
-
-### Example 3, filtering and sorting the collection
-
-```typescript
-// vm-collection.composable.ts
-
-export const useVmCollection = () => {
-  const collection = useXenApiCollection("VM");
-
-  return {
-    ...collection,
-    records: computed(() =>
-      collection.records.value
-        .filter(
-          (vm) =>
-            !vm.is_a_snapshot && !vm.is_a_template && !vm.is_control_domain
-        )
-        .sort((vm1, vm2) => vm1.name_label.localeCompare(vm2.name_label))
-    ),

+# Stores for XenApiRecord collections
+
+All collections of `XenApiRecord` are stored inside the `xapiCollectionStore`.
+
+To retrieve a collection, invoke `useXapiCollectionStore().get(type)`.
+
+## Accessing a collection
+
+In order to use a collection, you'll need to subscribe to it.
+
+```typescript
+const consoleStore = useXapiCollectionStore().get("console");
+const { records, getByUuid /* ... */ } = consoleStore.subscribe();
+```
+
+## Deferred subscription
+
+If you wish to initialize the subscription on demand, you can pass `{ immediate: false }` as options to `subscribe()`.
+
+```typescript
+const consoleStore = useXapiCollectionStore().get("console");
+const { records, start, isStarted /* ... */ } = consoleStore.subscribe({
+  immediate: false,
+});
+
+// Later, you can then use start() to initialize the subscription.
+```
+
+## Create a dedicated store for a collection
+
+To create a dedicated store for a specific `XenApiRecord`, simply return the collection from the XAPI Collection Store:
+
+```typescript
+export const useConsoleStore = defineStore("console", () =>
+  useXapiCollectionStore().get("console")
+);
+```
+
+## Extending the base Subscription
+
+To extend the base Subscription, you'll need to override the `subscribe` method.
+
+For that, you can use the `createSubscribe<XenApiRecord, Extensions>((options) => { /* ... */})` helper.
+
+### Define the extensions
+
+Subscription extensions are defined as `(object | [object, RequiredOptions])[]`.
+
+When using a tuple (`[object, RequiredOptions]`), the corresponding `object` type will be added to the subscription if
+the `RequiredOptions` for that tuple are present in the options passed to `subscribe`.
+
+```typescript
+// Always present extension
+type DefaultExtension = {
+  propA: string;
+  propB: ComputedRef<number>;
+};
+
+// Conditional extension 1
+type FirstConditionalExtension = [
+  { propC: ComputedRef<string> }, // <- This signature will be added
+  { optC: string } // <- if this condition is met
+];
+
+// Conditional extension 2
+type SecondConditionalExtension = [
+  { propD: () => void }, // <- This signature will be added
+  { optD: number } // <- if this condition is met
+];
+
+// Create the extensions array
+type Extensions = [
+  DefaultExtension,
+  FirstConditionalExtension,
+  SecondConditionalExtension
+];
+```
+
+### Define the subscription
+
+```typescript
+export const useConsoleStore = defineStore("console", () => {
+  const consoleCollection = useXapiCollectionStore().get("console");
+
+  const subscribe = createSubscribe<XenApiConsole, Extensions>((options) => {
+    const originalSubscription = consoleCollection.subscribe(options);
+
+    const extendedSubscription = {
+      propA: "Some string",
+      propB: computed(() => 42),
+    };
+
+    const propCSubscription = options?.optC !== undefined && {
+      propC: computed(() => "Some other string"),
+    };
+
+    const propDSubscription = options?.optD !== undefined && {
+      propD: () => console.log("Hello"),
+    };
+
+    return {
+      ...originalSubscription,
+      ...extendedSubscription,
+      ...propCSubscription,
+      ...propDSubscription,
+    };
+  });
+
+  return {
+    ...consoleCollection,
+    subscribe,
+  };
+});
+```
+
+The generated `subscribe` method will then automatically have the following `options` signature:
+
+```typescript
+type Options = {
+  immediate?: false;
+  optC?: string;
+  optD?: number;
+};
+```
+
+### Use the subscription
+
+In each case, all the default properties (`records`, `getByUuid`, etc.) will be present.
+
+```typescript
+const store = useConsoleStore();
+
+// No options (propA and propB will be present)
+const subscription = store.subscribe();
+
+// optC option (propA, propB and propC will be present)
+const subscription = store.subscribe({ optC: "Hello" });
+
+// optD option (propA, propB and propD will be present)
+const subscription = store.subscribe({ optD: 12 });
+
+// optC and optD options (propA, propB, propC and propD will be present)
+const subscription = store.subscribe({ optC: "Hello", optD: 12 });
+```
