chore(spec): regenerate the api-surface snapshot for the new ./ui export

`resolveI18nLabel (function)` on `./ui`. 0 breaking (nothing removed or
narrowed), 1 added — the delta `check:api-surface` asked for.

Regenerated only after a post-rebase `pnpm --filter @objectstack/spec build`:
run against the pre-rebase dist it also DROPPED `AuthoredRowWriteOperation` /
`AuthoredRowWriteVerdict` from `contracts.json`, which #6841 had added to the
source in the meantime — the AGENTS.md §9 stale-artefact trap, in mirror image.
