feat(rvw): complete journal config center MVP and tenant login routing

Deliver the RVW V4.0 journal configuration center across backend, frontend, migration, and docs with zh/en editorial baseline support and tenant-level prompt/template overrides. Unify tenant login to /:tenantCode/login and auto-enable RVW module when tenant type is JOURNAL to prevent post-login access gaps.
