## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
When a source has `snapshot.ok == false` or is missing entirely, panels currently just show "No data." with no indication of why. Distinguish three states visually:

1. **Not configured** — source disabled or `configured: false` → dim "—" or italic "not configured"
2. **Fetch error** — source enabled, snapshot exists, `ok: false` → `⚠` in border title + error message body
3. **No snapshot yet** — source enabled but no snapshot row → "waiting for first refresh…"

Implementation:
- In `payload()`, return a richer sentinel or pass state flags through
- Update each `DashPanel`'s border title with `⚠` prefix when `ok: false`
- Show the `snapshot.error` field in the panel body when available
<!-- SECTION:DESCRIPTION:END -->

## Acceptance Criteria
<!-- AC:BEGIN -->
- [ ] #1 Errored sources show ⚠ in panel border
- [ ] #2 Error message from snapshot is displayed in panel body
- [ ] #3 Not-configured sources are visually distinct from errored sources
- [ ] #4 Healthy panels are unchanged
