Addresses review on #27: canonicalize --history ("08" no longer hits
bash octal parsing), run the history jq in a plain command
substitution so a jq failure aborts under set -e, and restore the
schedule-guidance paragraph in OWNERSHIP_SELF_HOSTED.md.

- build-latest-ownership-snapshot.sh: discover with a wider limit and
add --history <n> to import the n previous supported above-1% XLSX
months (one per as-of date, oldest first) before the latest, so
`idx ownership changes` works straight from a synced snapshot.
- publish-ownership-snapshot.sh: pass --history through (for the
clan-private systemd timer via extraArgs).
- publish-ownership-snapshot.yml: `history` input (default 5).
- Docs: publish/self-hosted flow now describes the XLSX source,
observed upload days (2nd-3rd of the month), and --history.
