Immich Stats not working

### Description

Hi 👋
I’m trying to display Immich server statistics in Glance using the custom-api widget, based on the official community widget example, but I’m running into template evaluation errors and can’t get the stats to render.

**Setup**
- Glance version: v0.8.4 (binary, Linux amd64)
- Immich version: v2.5.x (Docker)
- Immich API endpoint: `/api/server/statistics`
- Auth: x-api-key header (API key works and endpoint returns valid JSON)

**What I’ve tried**
- Using .JSON.photos, .JSON.Int "photos", and similar variants
- Confirmed the API returns valid JSON
- Confirmed the API key and endpoint work outside Glance
- Restarted Glance and validated config loads without syntax errors

**Error shown in Glance UI / logs**
```
template: executing at <.JSON.photos>:
can't evaluate field photos in type glance.decoratedJSONResult
```

Any guidance or a working example would be greatly appreciated.
Thanks for all the work on Glance

Start with the linked Immich Stats widget and compare its template access with the response from /api/server/statistics, using the reported decoratedJSONResult error as the starting point. Done means a working example renders the returned statistics in Glance v0.8.4 with the x-api-key setup.
