Keep the top-level bucket creation introduced by PR #9653, since initialized DBs can still be missing newer buckets such as the historical channel bucket. Do not let the metadata bucket created during init make a fresh DB look initialized. Use strict metadata reads so a missing metadata/dbp key is distinct from a present DB version, then write metadata/dbp for genuinely fresh DBs. Existing DBs with a metadata bucket but missing metadata/dbp are left for the migration recovery path instead of being treated as latest.
