chore(devx): state the react-page-adapter rot record as data and retire its held allowance row (#15765)

The `scripts/**` symbol-anchor corpus (#15806) landed with two dated
`HELD_FILE_ALLOWANCES` rows for files live PRs held. PR #15770 landed, so the
row for `scripts/check-react-page-adapter-contract.mjs` is free — and an
allowance nobody retires is an exemption wearing a date.

The four dated readings in that gate's rot-record paragraph are now stated as
DATA — a small table with the file and the line number in separate cells —
never in `path:NNN` anchor form. The NUMBERS ARE NOT REPAIRED OR REPOINTED:
they are readings taken on a date, the paragraph's argument is unchanged, and
its ⛔ line still declares every number a record rather than a pointer. The one
substantive addition is that the paragraph no longer claims nothing resolves
citations in `scripts/**` — since #15806 something does, which is why the
anchor spelling had to go.

The self-test battery floor moves 34 → 30 because four of its cases are
registered PER allowance row; the reason is recorded next to the number so a
later reader cannot mistake the drop for cases that stopped running.
