fix: correct failing ADR-030 tests in field_model, longitudinal, and tomography

Browse Source 
Fix 4 test failures in the ADR-030 exotic sensing tier modules:

- field_model::test_perturbation_extraction: Use 8 subcarriers with 2
  modes and varied calibration data so perturbation on subcarrier 5
  (not captured by any environmental mode) remains visible in residual.

- longitudinal::test_drift_detected_after_sustained_deviation: Use 30
  baseline days with tiny noise to anchor Welford stats, then inject
  deviation of 5.0 (vs 0.1 baseline) so z-score exceeds 2.0 even as
  drifted values are accumulated into the running statistics.

- longitudinal::test_monitoring_level_escalation: Same strategy with 30
  baseline days and deviation of 10.0 to sustain z > 2.0 for 7+ days,
  reaching RiskCorrelation monitoring level.

- tomography::test_nonzero_attenuation_produces_density: Fix ISTA solver
  oscillation by replacing max-column-norm Lipschitz estimate with
  Frobenius norm squared upper bound, ensuring convergent step size.
  Also use stronger attenuations (5.0-16.0) and lower lambda (0.001).

All 209 ruvsense tests now pass. Workspace compiles cleanly.
