Compute empirical Green's function from cross-correlated grid noise.

Cross-correlates the 60 Hz signal recorded at two seismic
stations to extract the inter-station Green's function,
which encodes the near-surface velocity structure between
the stations.

Parameters (JSON body):
- station1_data : dict -- Filtered 60 Hz data at station 1 (required)
- station2_data : dict -- Filtered 60 Hz data at station 2 (required)
- frequency_60hz : float -- Fundamental grid frequency in Hz (default 60)

**Pricing:** Included in subscription tiers (legacy list price: GET /api/v1/billing/pricing).
