feat/show at_each_angle_hook in lamni tomo_parameters()

flomni's tomo_parameters() CLI printout already showed the active
at_each_angle_hook; lamni's didn't, making it easy to have a custom
per-projection hook active without noticing from the parameter dump.
Added the identical guarded print, reusing the shared
TomoQueueMixin._describe_active_hook() helper both classes already
inherit. Also switched lamni's tomo_scan() end-of-scan summary to use
that same helper instead of the raw attribute, matching flomni's
equivalent block and correctly flagging a stale/unregistered hook name.
