Incremental merge on top ofef701c8, which already integrated the earlier qyqy basebbf623a. qyqy_develop only added commits on top ofbbf623a, so this merge is conflict-free. Incoming: account/password login (POST /api/v1/auth/tokens), RBAC read-only query API, rate limit dependency, login test console and user management tools. Additive changes in app/main.py, requirements.txt and pyproject.toml from both sides are all preserved. ZSY side capabilities (visitor tokens, customer service agent, knowledge retrieval, profile projection) are unchanged.
