feat(auth,prompt-rule): add password change with session revocation and scope prompt rules by brand

Add self-service password change that re-hashes the credential and bumps a
per-user session version so all existing access/refresh tokens are rejected.
Session version is tracked in Redis with an in-memory fallback and enforced in
middleware and refresh.

Scope prompt rules and rule groups to a brand: new brand_id column (migrated to
a "未归属" fallback brand for existing rows), brand-filtered queries/indexes, and
brand-aware admin-web tabs.
