chore(lint): repoint check-route-envelope.mjs's ratchet owner to #9559

Both `ratchet:` fields in the route-envelope gate (`rest-server.ts`,
`error-response.ts`) named #7035, closed since 2026-08-10 (PR #7293, three
`/meta` 501 handlers converged — never the owner of "convert this file onto
the shared sendOk/sendError"). Triage executed option 1 at the triage layer:
#9559 is a `tracking` card that stays open while any `ratchet:` field names
it, with both legal exits (a dedicated envelope card, or the ADR-0112-D5
permanently-accepted path) written into it.

Repoints both fields from #7035 to #9559, preserving the option-1 prose
verbatim. Nothing else moves: no counter, threshold, or exempt entry changed
— confirmed by diffing the gate's own before/after output, which is
byte-identical except the citation. The eleven other `#7035` mentions in the
file are historical prose (what #7035 did, past tense) and are left alone.

Fixes #9461
