docs: update data-collection-reference and presentation for external dashboard parity

Browse Source 
- Fix validations_checked_total recording site (NetworkOPs, not LedgerMaster)
- Add Slide 11 to presentation: External Dashboard Parity overview with
  Mermaid diagrams for new metric categories, ValidationTracker sequence,
  and new dashboard summary

## Slide 11: External Dashboard Parity (Phase 7+)
### Bridging Community Monitoring into Native OTel
The community [xrpl-validator-dashboard](https://github.com/realgrapedrop/xrpl-validator-dashboard) provides 86 metrics for validator operators. We integrated the 29 missing metrics natively into the OTel pipeline.
### New Metric Categories
```mermaid
graph LR
subgraph "New Observable Gauges"
VH["Validator Health<br/>amendment_blocked, UNL expiry,<br/>quorum"]
PQ["Peer Quality<br/>P90 latency, insane peers,<br/>version awareness"]
LE["Ledger Economy<br/>fees, reserves, tx rate,<br/>ledger age"]
ST["State Tracking<br/>state value 0-6,<br/>time in state"]
VA["Validation Agreement<br/>1h/24h agreement %,<br/>agreements, misses"]
end
subgraph "Counters"
C1["ledgers_closed_total"]
C2["validations_sent_total"]
C3["state_changes_total"]
end
style VH fill:#1565c0,color:#fff
style PQ fill:#2e7d32,color:#fff
style LE fill:#e65100,color:#fff
style ST fill:#6a1b9a,color:#fff

style C1 fill:#37474f,color:#fff
style C2 fill:#37474f,color:#fff
style C3 fill:#37474f,color:#fff
```
### ValidationTracker — Agreement Computation
```mermaid
sequenceDiagram
participant C as RCLConsensus
participant VT as ValidationTracker
participant MR as MetricsRegistry
participant P as Prometheus
C->>VT: recordOurValidation(hash, seq)
Note over VT: Stores pending event
C->>VT: recordNetworkValidation(hash, seq)
Note over VT: Marks network validated
MR->>VT: reconcile() [every 10s]
Note over VT: After 8s grace period:<br/>both validated → agreed<br/>only one → missed<br/>5min late repair window
MR->>P: Export agreement_pct_1h/24h
```
### New Grafana Dashboards
| Dashboard | Key Panels |
| ---------------- | --------------------------------------------------- |
| Validator Health | Agreement %, amendment blocked, quorum, state value |
| Peer Quality | P90 latency, version awareness, upgrade recommended |
| Ledger Economy | Base fee, reserves, ledger age, transaction rate |
