Ports flomni's zero_deg_reference_at_each_subtomo to lamni's "8 equally
spaced sub-tomograms" mode: an extra dedicated projection at exactly 0
degrees before every sub-tomogram where the rotation naturally passes
back through 0, plus one final shot once the tomogram completes, for
tracking radiation damage over a long acquisition. lamni's tomo_type
2/3 already had the equivalent (golden_projections_at_0_deg_for_damage_estimation,
byte-for-byte identical to flomni's) -- only tomo_type 1 was missing.
_subtomo_starts_near_zero() uses subtomo_number % 2 (every odd
sub-tomogram) rather than flomni's 360-mode subtomo_number % 4 == 1 --
confirmed against lamni's actual rotation behavior rather than derived
from the position-array math, which doesn't cleanly split odd/even.
The GUI (tomo_params.py) needed no new UI code: _build_type1_section()
already gated this control on a per-setup has_zero_deg_reference flag,
so enabling it for lamni was just flipping that flag plus adding the
param name/default, mirroring flomni's entries exactly.
