- APIKey.alias (unique, required). Creating with an existing alias
renews that key: same key string kept, validity reset to 15d,
reactivated, name/roles updated (response has renewed=true).
- get_actor(): X-API-Key -> key alias, Bearer -> 'admin'.
- markdown & patch create/update record author / created_at /
updated_at / last_modified_by from the actor.
- Idempotent run_migrations() (information_schema-guarded ALTERs +
backfill) so existing tables/data gain the new columns on startup;
create_all still covers fresh DBs.

Add MarkdownPatch model (markdown_patch table, auto-created by
create_all) and /api/patch blueprint: list patches for a markdown
(inherits the parent's private/protected visibility), create/update
(admin|creator), delete (admin).
