Add network subgraph data staleness protection (#916)

* chore: log block number

* feat(monitor): add timestamp-based freshness validation for allocations

Prevent stale network subgraph data from replacing fresher data when the
Gateway routes queries to indexers synced to different blocks.

Acceptance rules:
- Fresh data (within max_data_staleness_mins): always accepted
- Stale but fresher than current best: accepted (improvement)
- Stale and not fresher than current: rejected

This ensures:
- Service always starts (any data beats initial state)
- Stale-but-better data progressively improves state
- Fresh data always wins (even with 0 allocations)
- Bad data never replaces good data

Add AllocationQueryResponse struct with block metadata, AtomicI64 to
track best known timestamp, and check_and_update_freshness() for
validation logic.

* chore: apply formatting
