The reverse-rename leg issued `wn_b groups rename` on Interop-02, but
Amethyst created Interop-02 — A is the admin, B is a plain member.
MIP-03's `enforceAuthorizedProposalSet` rejects any GroupContextExtensions
commit from a non-admin, so wn's rename was being dropped client-side,
the metadata commit never reached any relay, and Amethyst's UI (correctly
waiting for a kind:445 on Interop-02) never saw "Interop-02-reverse".
Split Test 07 into two separately-recorded legs so each uses a group
where the renamer is actually the admin:
07a — A (admin of Interop-02) renames to "Interop-02-renamed" via
the Amethyst UI; wn-side poll observes the new name.
07b — B (admin of Interop-03) renames to "Interop-03-renamed" via
`wn_b groups rename`; operator confirms Amethyst picked it up.
Each leg individually records pass/fail/skip so a missing GROUP_03
(Test 03 skipped) doesn't take out the whole test.
