docs: record live rollback drill pass in the release ledger

[crypticpy]

Updates the canonical release ledger (docs/release-readiness-status.md) so it no longer contradicts the BCHC drill inventory (raised by review on BCHC PR #37):

• RR-H02 — now complete for rc.6 and rc.7: v1.9.0-rc.7 consumed through the live updater (run 33144777338 → BCHC PR #34, maintainer-merged 929b007), and the live revert/rollback of an update PR is proven under RR-H07. Only the stable-tag run remains.
• RR-H07 — bad-deploy rollback upgraded from partial to passed: full on-GitHub drill on 2026-08-28 (BCHC PR #35 rollback to rc.6 through required checks + Pages redeploy + live smoke test; BCHC PR #36 roll-forward byte-identical to the maintainer-merged update, git diff 929b007 empty). Content takedown stays partial (protected-data history purge unrehearsed); credential-response and owner-transfer stay open.

BCHC's copy of this ledger syncs at the next template update (the stable v1.9.0 update PR). Docs-only change.

Reviewer's Guide

Updates the canonical release-readiness ledger to align with the BCHC drill inventory: rc.7 live consumption and update rollback are now evidenced, and the bad-deploy rollback drill is marked passed, while the stable-tag run and unrelated operational drills remain outstanding.
