- InitSchema migration now issues PRAGMA journal_mode = WAL after
PRAGMA foreign_keys = ON so fresh DBs are created in WAL mode.
- DatabaseInitService.init() also calls ensureWalMode() after
dataSource.initialize() so warm DBs (where migrations are skipped)
have WAL applied and persisted on every startup. Logs whether it
was already set or just enabled.
- main.ts now serves an OpenAPI 3.1 document at /api/docs and
/api/docs-json. A new toOpenApi31() utility converts the
NestJS-generated 3.0 document by setting openapi=3.1.0, normalising
the required info fields, and rewriting every legacy
'nullable: true' marker into a JSON Schema 2020-12 type union
('type: [<orig>, "null"]'). Recursion handles components, paths,
parameters, request bodies, response bodies, properties, items,
oneOf/anyOf/allOf, and parameter/request schemas.
- 7 new unit tests in tests/backend/openapi31.spec.ts lock the
conversion behaviour; total suite: 83 tests across 18 specs.
