Adds the two issues found and fixed during the release-candidate audit to release-candidate-review.md: the follow-up reminder index that never created on MariaDB (fix in the preceding commit), and the nondeterministic timeline day-grouping test. Corrects database-ownership.md drift: the MariaDB startup scenarios now report 42 tables (measured in every scenario this audit), not the stale 40 from before the last Phase 5 tables were added, and adds the partially-migrated heal scenario (35 -> 42) that was verified. All claims reflect behaviour verified in this audit: 420 tests on Windows and Linux in both ICU modes, all three Docker images built, four database startup scenarios against live MariaDB 11 and SQLite, and a full backup -> restore -> app-start cycle.
