fix(dogfood): move the D7 template-prompt row's tracker ids out of its runtime string

`check:doc-authoring`'s cross-package prose-id leg reds on a tracker id inside
a non-test string under packages/: the ledger `note` is runtime prose that
reaches authors, operators and generated surfaces, none of whom can resolve
one. The ruling id and its decision-batch number now live in an adjacent `//`
comment — the gate's own prescribed remedy; ADR-0049 stays in the string as a
customer-resolvable reference. No baseline entry: that file is maintainer-only
and shrink-only.
