feat/lamni tomogram timing overview + repeat-on-interruption

Port two flomni tomo_scan() behaviors lamni was missing: an end-of-scan
timing overview (total time, time excluding gaps, time lost to gaps,
sample/hook info) printed and written to scilog, and automatic repeat
of an entire projection when the beamline interlock trips mid-scan.

The latter needed two pieces together: enabling
bec.builtin_actors.scan_interlock at tomo_scan() start (previously
never enabled for lamni), and wrapping _tomo_scan_at_angle in
@scan_repeat so the resulting ScanRestart (or any other transient
exception) redoes the whole projection instead of aborting the scan.
A new LamNIError marks the one non-retryable case (unregistered
at_each_angle_hook), replacing a plain ValueError there.
