Yichen Jiang f5d21af60b test(ui-models): cover the failure paths, and share the one message reader
The per-file coverage gate caught three uncovered paths in the error handling
this round added: the page banner for a failed row removal, the editor card's
transport-rejection catch, and `store.fail` itself.

Two of them are one click each — Remove with a rejecting write, Apply with a
rejecting write — so they are covered through the UI rather than by calling
the helpers directly. The third was a duplicated `error instanceof Error ?
error.message : String(error)` in two files; it becomes one exported
`messageOf`, which removes the branch from both call sites and gives the
fallback arm a home a direct unit test can reach (the lint rule forbids
rejecting a promise with a non-Error, so a rejection cannot exercise it).
