can_view_tree() now distinguishes anonymous vs authenticated non-members so the
four-level model is enforceable:
- public / unlisted → anyone, including anonymous (unlisted gated only by the
link, so the API must never *list* it)
- site_members → any authenticated account (denies anonymous)
- private → members only
Members (any role) always view; soft-deleted trees stay hidden from everyone.
person_visibility (living-person redaction) is unchanged.
Tests: a full can_view_tree matrix across {anonymous, logged-in non-member,
member} × {public, unlisted, site_members, private}, plus deleted-tree-hidden
and the site_members anon-vs-logged-in case. Adds `engine`/`db_session` fixtures
(refactored out of `client`) so the engine can be unit-tested directly,
including the anonymous path that has no HTTP endpoint yet.

Fuzzy search: pg_trgm extension + trigram GIN indexes on name parts and a GET /trees/{id}/persons?q= search ranked by trigram similarity (finds Mueller for 'muller'), privacy-filtered. Living-person protection: the privacy engine now derives possibly-living status (explicit flag, else no death fact + birth within ~100y or unknown) and returns 'redacted' for non-members of public/unlisted trees; the service minimises those records ('Living person', no vitals). Members are unaffected. 31 tests pass.

Wires the data model through repository -> service -> API/v1. The privacy engine (app/services/privacy.py) is the single enforcement point: every read resolves visibility there (tree role, tree visibility, per-person override; living-person redaction is a marked Phase 2 TODO). All writes record an attributable AuditEntry.
Endpoints: POST /users (open dev bootstrap until auth), GET /users/me, POST/GET /trees, GET /trees/{id}, and POST/GET /trees/{id}/persons. Authn is a temporary X-User-Id header shim; authz is membership-based (owner/editor/viewer). Domain errors map to 401/403/404/409. Verified on the deploy target: private tree -> 403 for non-members, missing actor -> 401, audit log populated.
