docs(UAT_PLAYBOOK): document rbac auto-provision pre-condition for Better-Auth customers (GRO-2052)

QA review (PR #143) flagged UAT_PLAYBOOK.md update as the blocking item.
Adds a Pre-conditions sub-section covering TC-API-3.16/3.19a/b/c: test
users must have a Better-Auth 'user' row so resolveStaffMiddleware
auto-provisions a 'groomer' staff row before pets.ts runs the owner-bypass.

Includes a SQL verification query and the pre-fix 403 symptom to aid UAT
debugging.
