feat(lamni): skip opaque pixels in the smear min-projection
With the min-projection, the opaque sample holder rotating through the
X-ray eye view blackened every pixel it passed at any angle and shrank the
usable field of view. SmearComposite now ignores, per frame, pixels darker
than opaque_level (default 0.25) times the frame's 99th-percentile value
and takes the minimum over the remaining frames; pixels opaque at every
angle fall back to the plain minimum, and opaque_level=0 is the plain
minimum. opaque_level is passed through from
lamni.xrayeye_rotation_center_calibration_smear_experimental() and stored
in the calibration HDF5.

The smear capture-rate test now replaces the module's time instead of
patching time.time globally, which EPICS CA threads left running by other
tests also advanced.

Docs: smear opaque_level, LamNI optics in/out incl. central stop,
interferometer feedback commands, and moving to the scan centre including
the X-ray eye fit.
