test: pin Delaunay NaN lane isolation

[Jammy2211]

Summary

• pin production imaging and interferometer Delaunay JAX-likelihood scripts to exercise NaN callback-lane isolation introduced by PyAutoArray.

Cross-reference: PyAutoLabs/PyAutoArray#410.

Scripts Changed

• scripts/imaging/jax_likelihood/delaunay.py
• scripts/interferometer/jax_likelihood/delaunay.py

Upstream PR

PyAutoLabs/PyAutoArray#411

Test Plan

• Both changed scripts pass.
• Unchanged scripts/imaging/jax_grad/delaunay.py FD certification passes.
• Curated smoke: 20/21 passed; only unrelated scripts/imaging/subhalo_recovery.py reached its existing 300-second timeout, explicitly accepted by a human.
• Review: CLEAN.
• Heart: YELLOW reason set acknowledged by a human.
