Subject: [PATCH] fix(tui): separate rigs in the instance table (#2327)

The rig tui instance table drew a dotted rule between pods inside a rig but nothing between rigs, so one rig's last pod shared a block with the next rig's first pod, and trailing single-pod rigs ran together. Each rig boundary now gets a solid rule, and pods inside a rig keep the dotted rule. Source +4, tests +2.
