chore(spec): regenerate view.mdx on the merged tree and repair a renamed test helper

Discharges the os-regen deferral recorded by the merge commit.

content/docs/references/ui/view.mdx — re-derived with `gen:docs` from the merged
sources on a known-good base, rather than accepting what the merge driver left.
The driver had exited 0 while keeping the branch's blob verbatim and silently
dropping main's side; the merge commit took main's side per
`scripts/pm/os-regen-merge.sh` step 2, and this regeneration re-derives the
retirement's own rows on top. Both sides are present in the result.

packages/spec/src/ui/view.test.ts — main added a third `describe.each` site using
`viewDoorsCarryingPageMountCheck`, which this branch had renamed to
`viewDoorsCarryingObjectLevelChecks`. Both edits merged without a textual
conflict and left a dangling identifier; the rename is propagated to main's new
block. No behaviour change on either side.
