Review fix: reopened-record setup closes the database when seeding fails

Review round 5 (Codex gpt-5.6-terra, MEDIUM): the reopened-runtime
setup path leaked the just-opened connection if owner lookup or
seed_setup_admin raised, so HA's setup retries could accumulate open
handles. Seeding on that path is now wrapped symmetrically with the
first-setup path: any failure closes the database before re-raising,
with a test that fails seeding on a re-setup and asserts the close.
Suite: 909 passed.
