fix(ccd): update run_zone_ccd.py zone definitions to unified geometry

Browse Source 
Old zones (350-500, 500-700, 580-650) were based on pre-unification
illusion-only coordinates. Updated to match diagnose_corrections.py:
near_body 580-720, body_wake 720-850, sensor_zone 780-850.

"""Zone-wise CCD: force-CCD and signature-CCD per spatial zone.
Processes each of three spatial zones separately for illusion 0.75L and 1.0L:
- near_body: x[350:500] (envelope around pinball)
- body_wake: x[500:700] (body-connected near wake)
- sensor_zone: x[580:650] (around sensor plane at x=30*L0=600)
Processes each of three spatial zones separately for illusion 0.75L and 1.0L

- body_wake: x[720:850] (body-connected near wake)
- sensor_zone: x[780:850] (around sensor plane at x=40*L0=800)
For each zone: mask the snapshot matrix to keep only grid points in the zone,
build a target-only POD basis, project correction fields, and compute
