refactor: deduplicate Live construction by having _restart_compact_unlocked delegate to _start_compact_live_unlocked

Both _restart_compact_unlocked and _start_compact_live_unlocked built
identical Live objects (same console, transient=True, refresh rate).
Having _restart_compact_unlocked call _start_compact_live_unlocked
eliminates the duplication so any future change to Live parameters
(e.g. refresh rate) only needs to happen in one place.
