Add new experiments and analysis scripts for dropzero features

- Introduced `fused_importance_with_axial.py` to evaluate the importance of Axial_Length in the fused-head model.
- Created JSON configurations for various experiments excluding zero-importance clinical features:
  - `cd_solo_bilateral_dropzero.json`: Bilateral clinical-only evaluation.
  - `cd_solo_single_dropzero.json`: Single-eye clinical-only evaluation.
  - `ensemble_refugelike_ckpt_dropzero.json`: Ensemble model with dropped zero-importance features.
  - `ensemble_single_refugelike_dropzero.json`: Single-eye ensemble model with dropped features.

"""F4 Bilateral lift via confidence strips.
"""F4 (main text) - Bilateral clinical, image, and Hadamard L2 fusion.
Six-panel grid in the same v3-style as F3. Rows are aggregation mode,
columns are tower configuration:
Patient-level analogue of F3: same two-row / three-column layout, same pruned
clinical panel, but every column is the bilateral (both-eyes) model reading
from the patient-level 'hb' stage. All three columns share the pruned clinical
panel: astigmatism, dioptre_1, dioptre_2, and Phakic/Pseudophakic dropped
(see S8e). The image column has no clinical inputs so is unaffected by the
prune.
Clinical Image Fusion (img+cd)
Single | cd_solo_single | img_solo_single | ensemble_single (Hadamard L1)
Bilateral| cd_solo_bilat | img_solo_bilat | baseline_ensemble (L2 concat default)
Columns (left -> right):
Clinical only (bilateral) (cd_solo_bilateral_dropzero, hb)
Image only (bilateral) (img_solo_bilateral_refugelike, hb)
Hadamard L2 fusion (bilateral) (ensemble_refugelike_ckpt_dropzero, hb)
All refugelike. Single-eye panels eval at the appropriate eye-level fusion
stage; bilateral panels eval at hb. Points are coloured by VF-MD severity.
Each panel shows per-patient or per-eye P(Glaucoma) with TN / TP rates and
AUC printed in.
Rows:
top: confidence strip - predicted P(Glaucoma) coloured by VF-MD tier
(severe / moderate / early) with normals in grey. Patients are the
unit of prediction here (~1 prediction per patient per fold-rep).
bottom: ROC per severity tier, each tier vs all normals; pooled ROC curve
with a 95% CI band from patient-level bootstrap; pooled AUC with
95% CI annotated.
Re-run anytime:
Glaucoma - VF_MD not recorded is dropped from both rows (n = 0 patients at
the patient-worst-eye level).
Re-run:
