[Snapshot and restore] fix restore status tab for system indices (#232839)

fixes #228531

add expand_wildcards parameter and clear mocks

- Add `expand_wildcards: 'all'` to indices.recovery call in
server/routes/api/restore.ts
- Add beforeEach hook to clear all mocks in restore.test.ts
- Add test case to verify expand_wildcards parameter usage in
restore.test.ts

## How to verify

### Before Fix State

First run local es/kibana. Set `path.repo` config setting.

You can do it in `elasticsearch.yml` or simply from cli passing `-E`
flag

For example:

```bash
yarn es snapshot -E path.repo=/tmp/snapshots # run es in one window
yarn start --no-base-path # run kibana in the other
```

After kibana/es are ready

Do this to test the before state (on main branch for example)
```graphql

# Create a test repository (filesystem type for simplicity) (once)
PUT _snapshot/test_repo
{
  "type": "fs",
  "settings": {
    "location": "/tmp/snapshots"
  }
}

# Create a regular index/populate it
PUT test_index/_doc/1
{
  "data": "regular index"
}

# Create a system index
PUT .test_system_index
{
  "settings": {
    "index.hidden": true
  }
}
# Populate it as well
PUT .test_system_index/_doc/1
{
  "data": "system index"
}

# Create a snapshot including system indices
PUT _snapshot/test_repo/snapshot_with_system?wait_for_completion=true
{
  "indices": ["test_index", ".test_system_index"],
  "include_global_state": false,
  "expand_wildcards": "all"
}

# Delete both indices to prepare for restore
DELETE test_index
DELETE .test_system_index

# Check that they are gone
GET test_index
GET .test_system_index

# Restore system index
POST _snapshot/test_repo/snapshot_with_system/_restore
{
  "indices": ".test_system_index"
}
```

Now go to `app/management/data/snapshot_restore/restore_status` and
observe no restored snapshot

/>


### After Fix State

Checkout PR branch repeat the same kibana/es setup steps

Go to devtools
```
# resetting state
DELETE _snapshot/test_repo/snapshot_with_system?wait_for_completion=true
```

The rest is the same

The restore status tab should show
