"""Integration tests for BuhApp backend API.

Coverage:
- health & legal
- auth: register, login, duplicate, invalid JSON, missing consents, validation, /me, /auth/consents
- users: public profile by id, bad uuid, update /me, prefs GET/PUT, location PUT, visibility PUT,
         search nearby (with and without params)
- chats: ensure (idempotent + self-chat + blocked), list, access by non-member, messages
         (send/edit/delete), mark read
- reviews: create (happy + duplicate + bad rating + non-member), list, stats
- blocks: create / list effect on ensure-chat / unblock
- reports: create (multiple target types + bad target_type)

Edge cases are mixed into the same file via descriptive names so they show up
clearly in the pytest output.

Run:
    pytest tests/ -v
    pytest tests/ -v --tb=short
