chore(issues): record the mirror addresses from the first full run

The mirror created the seven issues that had never reached the board
(management#33-39) and wrote each new iid back into its file. Without the
writeback the next run would create duplicates instead of recognising its own
work.

Group check after the run: the issue drift class is empty - 27 findings down to
20, 7 hints to 0, and not a single GitLab issue without a canonical file. What
remains is unrelated to the board: seventeen commit-hygiene findings parked in
#0053 and three component declarations.
